For a diesel truck, the right performance exhaust system depends on your vehicle, intended sound, and whether you want a complete bolt-on kit or a component for a custom build. My best overall pick is the MagnaFlow Performance DPF Back Exhaust System Kit 17912, a vehicle-specific option that keeps the comparison focused on a matched system rather than a standalone muffler. The MBRP S5247304 stands out as a stainless cat-back choice for select Ford gas trucks, while the MagnaFlow mandrel-bent dual kit suits buyers who want a dual-exhaust layout. The main tradeoffs are fitment certainty and system completeness versus flexibility, sound changes, and installation work. Read on for the full breakdown and a guide to choosing the right setup for your truck.

Key Takeaways
- Complete, vehicle-specific kits rank ahead of loose components for most buyers: MagnaFlow 17912, MBRP S5247304, PHILTOP, and Part Synergy specify vehicle applications, while the universal mufflers require a custom fit plan.
- Fitment is not interchangeable across diesel trucks: the MBRP S5247304 is listed for 2017-and-up Ford F-250/F-350 models with a 6.2L engine, so it is not a diesel-specific recommendation despite appearing in this roundup.
- Universal mufflers are component choices, not full performance systems: LCGP, Upower XS2772, and the other 4-inch straight-through muffler can suit fabrication projects, but do not provide a complete truck-specific exhaust.
- The stack kit and dual-exhaust kit prioritize different layouts: the 5-inch Smoker stack kit is for buyers seeking a conspicuous stack configuration, while the MagnaFlow dual kit is aimed at a dual outlet arrangement without supplied tips.
- Product naming alone cannot confirm emissions legality or performance gains: check the exact truck, emissions equipment, included hardware, and local requirements before ordering any exhaust part.

MagnaFlow Performance DPF Back Exhaust System Kit 17912
I rank the MagnaFlow 17912 as the strongest choice here for a late-model Ram owner seeking a vehicle-specific DPF-back system rather than a universal component. Its stated fitment covers 2019–2026 Ram 2500 and 3500 6.7L trucks, and the single passenger-side rear exit keeps the layout straightforward. Compared with the MBRP S5247304, which is a cat-back system for specified Ford 6.2L trucks, this kit serves a different diesel application and is identified as DPF-back. The stainless-steel construction suits owners prioritizing corrosion resistance, but the listing does not give tubing diameter, sound level, or detailed installation guidance. Its narrow fitment also rules it out for other trucks, while the universal LCGP muffler is more adaptable as a component when a full vehicle-specific kit is not needed.
Pros:- Specified fitment for 2019–2026 Ram 2500 and 3500 6.7L models
- Stainless-steel construction
- DPF-back system format
- Single passenger-side rear exit gives the system a clearly defined routing layout
Cons:- Fitment is limited to the listed Ram applications
- The supplied product information does not state tubing diameter or sound characteristics
- Detailed installation instructions are not provided in the available product data
Best for: Owners of 2019–2026 Ram 2500 or 3500 trucks with the 6.7L diesel who want a stainless DPF-back system with a defined rear-exit layout.
Not ideal for: Owners of other truck makes or model years, or buyers who need published tubing dimensions, sound information, or detailed installation instructions before choosing.
- Model:17912
- System type:DPF-back exhaust system
- Material:Stainless steel
- Fitment:2019–2026 Ram 2500/3500 6.7L
- Exit:Single passenger-side rear
- Size:One size
Our verdict“Choose the MagnaFlow 17912 if your late-model Ram 6.7L matches the listed fitment and you want a stainless DPF-back kit rather than a universal muffler.”
5” Turbo Dual Smoker Diesel Exhaust Stack T Pipe System Kit
This kit is the most visually distinctive option in the group: its dual curved chrome stacks and 60-inch pipes are intended for a custom truck setup, not a discreet replacement exhaust. The 5-inch diameter and mandrel-bent tubing are presented as flow-focused features, while the polished finish makes the stacks a visible styling choice. Compared with the vehicle-specific MagnaFlow 17912, this kit lists compatibility across Dodge, Chevy, and Ford trucks but does not identify exact models or year ranges, so buyers need to verify fit and routing before ordering. At 92.4 pounds, it is much heavier than the MBRP cat-back listed here and calls for secure mounting. Professional installation is recommended; this is a poor match for buyers seeking a simple bolt-on rear-exit system or a subtle appearance.
Pros:- Dual curved pipes create a distinct stack-style appearance
- Five-inch pipe diameter with mandrel-bent tubing
- Polished chrome-plated finish
- Listed for Dodge, Chevy, and Ford trucks
Cons:- At 92.4 pounds, the kit needs strong, secure mounting
- Universal brand-level compatibility does not specify exact truck models or years
- Professional installation is recommended for routing and support
Best for: Truck owners planning a custom dual-stack build who want polished 5-inch pipes and can confirm fitment and mounting with an installer.
Not ideal for: Drivers seeking an exact vehicle-specific kit, a low-profile exhaust, or an installation that avoids custom routing and sturdy stack supports.
- Material:Alloy steel
- Finish:Chrome-plated, polished
- Inlet diameter:5 inches
- Pipe diameter:5 inches
- Pipe length:60 inches
- Overall length:60 inches
- Thickness:1.6 mm
- Weight:92.4 pounds
- Compatible vehicles:Dodge, Chevy, and Ford trucks
Our verdict“Pick this kit for a custom stack-style truck build, not for a straightforward, model-specific exhaust replacement.”
MBRP S5247304 Exhaust System Cat Back for 2017-UP Ford F250/350 6.2L Super/Crew Cab 4″ Single Side T304
The MBRP S5247304 stands apart as a vehicle-specific cat-back system for 2017-and-newer Ford F-250/F-350 6.2L Super/Crew Cab trucks. Its T304 stainless steel construction and 4-inch tubing make it a more defined full-system choice than the universal LCGP or Upower mufflers, which are components for existing 4-inch exhaust setups. The single-side exit keeps the configuration simpler than the dual-stack kit, although it will not deliver that custom stack appearance. The product description says the system is intended to improve exhaust flow and reduce temperatures, but it does not provide measured results or sound levels. Its stated Ford 6.2L fitment is specific, and the 51-pound assembly may need support; diesel buyers should verify engine compatibility rather than assume the F-250/F-350 designation alone is enough.
Pros:- Cat-back system with stated fitment for specified Ford F-250/F-350 6.2L trucks
- T304 stainless-steel construction
- Four-inch tubing and single-side exit
- Full system option rather than a standalone universal muffler
Cons:- Fitment is limited to the listed Ford engine and cab applications
- The 51-pound system may require additional support
- The product data gives no measured performance or sound figures
Best for: Owners of a 2017-or-newer Ford F-250 or F-350 6.2L Super/Crew Cab who want a specified-fitment cat-back system in T304 stainless steel.
Not ideal for: Diesel owners whose truck has a different engine or cab configuration, or buyers who want a documented sound level, lighter components, or a dual-exit design.
- Brand:MBRP
- Part number:S5247304
- System type:Cat-back exhaust system
- Material:T304 stainless steel
- Tubing diameter:4 inches
- Exit:Single side
- Fitment:2017-UP Ford F-250/F-350 6.2L Super/Crew Cab
- Weight:51 pounds
Our verdict“Choose this MBRP system only if your Ford 6.2L truck matches the stated application and a single-side cat-back layout suits your build.”
LCGP 4-Inch Diesel Exhaust Muffler, Stainless Steel, Universal Resonator, 30-Inch Length
The LCGP is a universal 4-inch straight-through muffler, not a complete exhaust kit, which makes it a better fit for someone modifying an existing system than for a buyer who wants a vehicle-specific bolt-in upgrade. Its stainless-steel body and 4-inch inlet and outlet suit setups built around that pipe size, while the 30-inch overall length gives an installer a defined space requirement. The product description associates the straight-through design with improved flow and a deep tone, but provides no measured flow or sound data. Compared with the MBRP S5247304, it offers broader component-level flexibility but lacks a full system and vehicle-specific fitment. It also shares its basic dimensions with the Upower XS2772, so buyers should compare construction details and confirm that either muffler fits their intended layout.
Pros:- Stainless-steel construction
- Four-inch inlet and outlet for compatible exhaust piping
- Straight-through design
- Can be installed with welding or clamps
Cons:- Muffler only, not a complete exhaust system
- Requires welding or clamps and may need professional installation
- No measured flow, sound, or vehicle-specific fitment data is supplied
Best for: Truck owners or exhaust shops replacing or fabricating around a 4-inch system who need a stainless straight-through muffler and can handle clamp or welded installation.
Not ideal for: Buyers looking for a complete vehicle-specific exhaust kit, a muffler for another pipe size, or a no-fabrication installation.
- Inlet diameter:4 inches
- Outlet diameter:4 inches
- Body length:24 inches
- Overall length:30 inches
- Body width:7 inches
- Material:Stainless steel
- Design:Straight through
- Installation:Welding or clamps required
Our verdict“Choose the LCGP if you are adapting a 4-inch exhaust and want a standalone muffler, rather than a complete system like the MBRP.”
Upower 4″ Inlet Diesel Exhaust Muffler 7″ x 24″ Body 30″ Whole Length XS2772 – Straight Through Stainless Steel Welded Resonator
Upower’s XS2772 is another standalone straight-through muffler, but its listing emphasizes a welded construction and a 7-inch round body. That makes it a natural candidate for a fabricated 4-inch exhaust where the installer plans to weld the component into place. Its stainless-steel build, 24-inch body, and 30-inch overall length align closely with the LCGP muffler, so dimensions alone do not make this a clear alternative; installation preference is the more useful distinction. The LCGP explicitly lists welding or clamps, while Upower describes welded construction, which may suit a permanent fabrication but offers less stated flexibility. Neither replaces a complete system like the MBRP cat-back, and this model is limited to 4-inch piping. Buyers should confirm space and connection needs before committing.
Pros:- Stainless-steel construction
- Straight-through design
- Welded construction suits permanent exhaust fabrication
- Four-inch inlet and outlet for compatible systems
Cons:- Requires welding skill or a professional installer
- Limited to 4-inch exhaust piping
- Standalone muffler rather than a complete vehicle-specific system
Best for: Owners or fabricators building a 4-inch truck exhaust who prefer a stainless welded resonator with a straight-through layout.
Not ideal for: Drivers who need a complete vehicle-specific exhaust, want clamp-install flexibility clearly specified, or have piping other than 4 inches.
- Model:XS2772
- Inlet diameter:4 inches
- Outlet diameter:4 inches
- Overall length:30 inches
- Body length:24 inches
- Body type:7-inch round
- Material:Stainless steel
- Design:Straight-through, welded construction
- Application:Universal fit for 4-inch exhaust pipes
Our verdict“Choose the Upower XS2772 for a fabricated 4-inch system where welded installation is preferred; choose a complete kit if you need vehicle-specific components.”
PHILTOP Cat-Back Exhaust System for 2011-2014 Ford F-250/F-350 Super Duty V8 6.7L
The PHILTOP is the most direct choice here for owners of a 2011–2014 F-250 or F-350 6.7L who want a complete cat-back system rather than a replacement muffler or a fabrication project. Its T-304 stainless steel construction is a stronger corrosion-resistance proposition than the Part Synergy kit’s aluminized steel, while the stated bolt-on installation is far less involved than the Magnaflow dual kit’s professional-installation requirement. The system is described as reducing back pressure and changing exhaust sound, but the supplied details do not quantify power gains or sound level. Its main limitation is fitment: it is not a universal upgrade, and buyers with other model years or engines should look elsewhere. The two-year warranty adds a defined support period, though this remains a narrow-fit pick rather than a flexible platform upgrade.
Pros:- T-304 stainless steel offers corrosion resistance for long-term exhaust-system use.
- Cat-back configuration provides a complete system rather than a muffler-only replacement.
- Bolt-on installation is less involved than the fabrication needed for the Magnaflow dual kit.
- Two-year warranty is longer than the Part Synergy kit’s stated 30-day return period.
Cons:- Fitment is limited to 2011–2014 F-250/F-350 trucks with the 6.7L V8.
- The product details provide no quantified horsepower, torque, or sound-level data.
- Stainless construction may cost more than a basic replacement exhaust.
Best for: Owners of 2011–2014 Ford F-250 or F-350 Super Duty trucks with the 6.7L V8 who want a stainless cat-back system designed for bolt-on installation.
Not ideal for: Owners of different Super Duty model years or engine sizes, and buyers seeking a universal muffler or a system with documented power-gain figures.
Our verdict“Choose the PHILTOP if your truck matches the listed 6.7L fitment and you want a corrosion-resistant cat-back with bolt-on installation.”
Part Synergy Replacement Exhaust System Kit for 99-03 F250 F350 7.3L Powerstroke
For a 1999–2003 F-250 or F-350 7.3L owner replacing a worn system, the Part Synergy kit prioritizes direct-replacement fitment over a performance-focused material upgrade. Its compatibility with all cab and bed configurations makes it more adaptable within its stated truck range than the narrowly fitted PHILTOP system, which serves only 2011–2014 6.7L models. The tradeoff is aluminized steel rather than the PHILTOP’s T-304 stainless, so buyers focused on corrosion resistance may prefer that option if their truck fits. This kit is described as easy to install and suited to reliable operation, but the supplied data does not specify pipe diameter, exhaust tone, or measured performance changes. Its 30-day return warranty is also a short support window, making fitment confirmation especially important before purchase.
Pros:- Designed as a direct replacement for the stated 7.3L truck applications.
- Fits all cab and bed configurations within the listed 1999–2003 F-250/F-350 range.
- Aluminized steel provides a practical replacement-system construction.
- Installation is described as easy, without a stated need for fabrication.
Cons:- Aluminized steel is a less corrosion-focused choice than the PHILTOP’s T-304 stainless.
- The stated warranty is limited to a 30-day return period.
- No pipe diameter, sound character, or measured performance figures are provided.
Best for: Owners of 1999–2003 F-250 or F-350 7.3L Powerstroke trucks who need a replacement system that accommodates different cab and bed configurations.
Not ideal for: Buyers prioritizing stainless-steel corrosion resistance, a longer stated warranty, or documented exhaust-flow and sound specifications.
Our verdict“Pick Part Synergy for a straightforward replacement on a compatible 7.3L truck, but choose a stainless option if corrosion resistance is your priority.”
4 Inch Diesel Muffler Exhaust, 4″ Inlet 4″ Outlet Straight Through Resonator, 7″ x 24″ Body, 30″ OAL, Stainless Steel Muffler for Truck
This product is a standalone 4-inch muffler, not a complete exhaust system, so it suits buyers changing a compatible truck’s sound or flow without replacing the full exhaust. Its straight-through design and stainless construction distinguish it from the Part Synergy replacement kit, which is a full system for specific older Ford diesels. The 4-inch inlet and outlet make pipe compatibility a firm requirement; this is not a universal fit simply because it is marketed for trucks. The listed 7-by-24-inch body and 30-inch overall length give installers useful sizing information, and hardware is described as included. However, the straight-through layout may be too loud for drivers seeking a quieter, restrained tone, and the product data gives no vehicle-specific fitment list or quantified performance results. Buyers should confirm dimensions and installation needs before choosing it over a complete cat-back option such as PHILTOP.
Pros:- Four-inch inlet and outlet suit compatible large-diameter exhaust piping.
- Stainless-steel construction is intended to resist corrosion.
- Straight-through internal design prioritizes exhaust flow.
- The stated body and overall dimensions help with fitment checks.
Cons:- It is a muffler, not a complete cat-back or replacement exhaust system.
- No truck-specific year, make, or model fitment list is supplied.
- Straight-through design may produce more sound than some drivers want.
Best for: Diesel-truck owners with compatible 4-inch exhaust piping who want to replace the muffler alone with a stainless straight-through design.
Not ideal for: Buyers who need a complete vehicle-specific exhaust kit, have piping other than 4 inches, or prefer a quieter exhaust tone.
Our verdict“Choose this muffler when you want a stainless 4-inch straight-through replacement and have confirmed that its dimensions match your truck.”
All-Stainless Magnaflow Mandrel-Bent Performance Dual Truck Exhaust Kit without Tips
The Magnaflow kit is the most involved option in this group: it pairs an all-stainless dual-exhaust layout with mandrel-bent tailpipes and a Magnaflow 12198 muffler, but it is listed for gas-powered light- and medium-duty trucks, not diesel applications. That distinction matters in a roundup about diesel performance exhausts: despite the broad truck fitment wording, this is not the straightforward diesel choice offered by the PHILTOP or the 7.3L Part Synergy kit. Its two 45-degree turnouts and dual routing suit a custom appearance and sound-focused build, while mandrel bends are intended to limit restriction through the pipe bends. In exchange, it requires professional installation and may need fabrication; clamps, hangers, and tips are not included. I would shortlist it only for a compatible gas truck project, not as a diesel performance recommendation.
Pros:- All-stainless construction is intended to resist corrosion.
- Mandrel-bent tailpipes are designed to reduce restriction through bends.
- Magnaflow 12198 muffler and dual 45-degree turnouts support a custom exhaust layout.
- The listed compatibility covers several gas-truck families, subject to stated exclusions.
Cons:- Listed for gas models, so it is not a suitable diesel-specific recommendation.
- Professional installation is required and fabrication may be necessary.
- Clamps, hangers, and tips are not included.
Best for: Owners of compatible 1988–2018 gas-powered light- or medium-duty trucks planning a custom dual-exit build and willing to arrange professional installation.
Not ideal for: Diesel-truck owners seeking a diesel-specific performance exhaust, or buyers who need a complete direct-fit kit with installation hardware and tips included.
Our verdict“Consider this kit only for a compatible gas-truck custom build; diesel owners should choose an exhaust specified for their engine and application.”
How We Picked
I ranked these options by how directly they serve a buyer seeking a performance exhaust system for a diesel truck, giving priority to complete systems with a stated vehicle application over universal mufflers that need additional fabrication. I also weighed the practical value of the system format—DPF-back, cat-back, replacement, stack, dual, or muffler-only—because those formats change installation scope and what the buyer receives. Fitment specificity mattered, as did the material or construction details provided in the product name.
The lineup has important limitations: several entries are universal components, and the MBRP listing specifies a 6.2L Ford application rather than a diesel engine. I have not treated product titles as proof of horsepower gains, sound level, emissions compliance, or exact kit contents. The ranking reflects relevance and clarity for the stated use case, not claimed test results; buyers should verify their exact engine, cab, bed, emissions configuration, and included parts before purchase.

Factors to Consider When Choosing Performance Exhaust Systems For Diesel Trucks
Before choosing from these performance exhaust systems for diesel trucks, decide whether you need a complete replacement path or just a component for a custom setup. The right answer often depends more on truck-specific fitment and emissions equipment than pipe diameter or sound claims.
Match the Kit to Your Exact Truck and Engine
Start with the truck’s model year, engine, cab, bed, drivetrain, and existing exhaust configuration, then compare each detail with the manufacturer’s fitment notes. A kit listed for a Ford Super Duty does not automatically fit every Super Duty, and the MBRP entry here is specified for a 6.2L engine, not a diesel. Similar-looking model names can cover different chassis or exhaust routing. A fitment error can turn a bolt-on purchase into a fabrication job or leave you with parts that cannot be installed. When a listing is vague, confirm the part number and application with the seller or manufacturer before ordering.
Know What DPF-Back, Cat-Back, and Replacement Mean
System labels describe where the kit begins and what components it replaces, so they affect both installation and compatibility. A DPF-back kit is designed to connect downstream of the diesel particulate filter, while a cat-back label generally refers to the section after a catalytic converter and may be more common on gasoline applications. A replacement kit may focus on restoring an existing layout rather than changing its flow path or sound. Do not assume that a cat-back or replacement system removes emissions hardware; check the included sections and applicable rules. If your goal is a straightforward upgrade, a complete kit matched to your truck is usually less uncertain than combining unrelated components.
Treat Universal Mufflers as Fabrication Components
A universal muffler can be a sensible choice when a shop is building or repairing a custom exhaust, but it is not a complete system. Confirm inlet and outlet diameter, body dimensions, overall length, orientation, clearance, and the space available under the truck. Pipe size alone does not establish performance: a poorly matched muffler or routing change can create fitment problems without delivering the result you expect. Budget for any required pipe, hangers, clamps, welding, and professional labor. Buyers who want a more predictable installation should favor a vehicle-specific kit over the LCGP, Upower, or other standalone muffler options.
Choose Sound and Layout Before Chasing Diameter
Decide whether you want a restrained factory-like tone, a more noticeable exhaust note, a rear or side exit, or a vertical stack layout before comparing pipe sizes. The 5-inch Smoker stack kit represents a very different visual and routing choice from a conventional single-side system or the MagnaFlow dual layout. Sound can vary with the engine, cab, muffler, and exhaust routing, so a product title is not a reliable promise of cabin drone or exterior volume. Look for sound information tied to your exact truck, and check local noise rules if a louder setup is part of the plan. Choose a layout that suits daily use, towing, parking, and the truck’s intended appearance.
Check Materials, Hardware, and Long-Term Service Needs
Stainless construction can help resist corrosion, but material descriptions differ and do not tell the whole story about thickness, weld quality, or hardware. Ask what the kit includes: pipes, muffler, clamps, hangers, tips, and installation instructions can vary. The MagnaFlow dual kit is described as being supplied without tips, which may mean extra parts or a different finished look than expected. Consider road salt, moisture, and how easily the system can be inspected or serviced. A complete, well-matched kit may be a better ownership choice than a cheaper component that needs additional parts and labor.
Verify Emissions Rules and Realistic Performance Expectations
Exhaust changes can intersect with emissions regulations, inspection rules, and warranty conditions, particularly on modern diesel trucks with aftertreatment equipment. Confirm that a proposed system retains required equipment and is legal where the truck is registered and driven. Do not treat words such as “performance” or “straight-through” as proof of a specific horsepower, torque, fuel economy, or towing improvement. Results depend on the full vehicle setup, and many listings do not provide controlled, application-specific data. If compliance is a priority, seek written confirmation for your truck and region before buying.
Frequently Asked Questions
Can I use the MBRP S5247304 on a diesel Ford Super Duty?
The listed application specifies 2017-and-up Ford F-250/F-350 trucks with a 6.2L engine, so the product information provided does not identify it as a diesel fit. Do not infer diesel compatibility from the truck model alone; Ford offered different engines with different exhaust layouts. Check the exact part number against your engine and model year before purchase. If you have a diesel, choose a kit explicitly listed for that diesel application or get confirmation from the manufacturer.
Is a universal 4-inch muffler enough to replace my truck’s exhaust system?
No: the LCGP, Upower XS2772, and similar entries are muffler components, not complete truck-specific systems. You may also need compatible pipe, hangers, clamps, and fabrication to connect the part to your existing exhaust. Whether it can replace your muffler depends on the truck’s pipe size, available clearance, and connection style. If you want a more direct installation, compare complete kits listed for your exact vehicle instead.
Will a DPF-back exhaust keep my diesel emissions equipment in place?
A DPF-back label generally describes a system intended to connect after the diesel particulate filter, but the label alone does not confirm every included part or local compliance. Review the installation diagram and product documentation to see exactly where the kit begins and whether factory aftertreatment remains untouched. Rules and inspection requirements vary by location and truck use. Ask the manufacturer for written application and compliance details if you need the system to remain emissions-legal.
Should I choose a complete kit or a standalone muffler for a custom build?
A complete kit makes more sense when you want parts designed around a stated truck application and prefer fewer decisions about routing and connections. A standalone muffler can suit a custom exhaust when a fabricator can confirm its dimensions, placement, and compatibility with the rest of the system. Compare the full installed scope, including extra tubing, hangers, clamps, welding, and labor, rather than comparing only the listed component. If you lack a clear fabrication plan, a vehicle-specific kit is usually the simpler route.
What should I verify before ordering a stack or dual exhaust kit?
Confirm that the kit fits your exact year, engine, cab, bed, and chassis, then check its routing and exit location against the truck’s body and intended use. A stack setup has different clearance, appearance, and installation implications from a conventional rear or side exit. For a dual kit, check whether tips are included; the MagnaFlow dual option here is listed without tips. Also review local noise and emissions requirements, since a distinctive layout does not exempt the system from applicable rules.
Conclusion
For most buyers seeking a complete, diesel-relevant option, I would start with the MagnaFlow Performance DPF Back Exhaust System Kit 17912 as the best overall pick, subject to exact fitment and emissions checks. The best value depends on your truck and installation plan: a vehicle-specific replacement such as Part Synergy may suit a 1999–2003 7.3L Powerstroke owner, while universal mufflers make sense only when you already have fabrication support. For a premium-style dual layout, consider the all-stainless MagnaFlow mandrel-bent dual kit, while confirming what is supplied since tips are not included. Beginners should favor a complete kit with clearly verified fitment rather than a standalone muffler. For a stack configuration, the 5-inch Smoker kit is the specialized choice; for any other buyer, match the exact engine and exhaust format first, and skip the MBRP listing unless its 6.2L application fits your truck.
