Best Universal Dual Exhaust Kit for Custom Builds and Trucks

#1 · Best Overall

1. Flowmaster 15936 U-Fit

• Material: Plastic
• Material Type: Plastic
• Installation Type: Bolt-On

Best for: 2.5-inch custom exhaust builders.

Why it ranks #1: The universal 16-piece kit has 2.5-inch mandrel-bent tubing, over-the-axle pipes, optional exits, and slip-fit connectors, although it includes pipes only.

Over-the-axle pipes with optional tailpipe exits give Flowmaster’s 16-piece, 2.5-inch U-Fit kit a useful foundation for custom dual-exhaust routing. Its front adapters, intermediate pipe, and H-pipe extend the assortment beyond basic straight sections, enabling builders to plan a more complete pipe layout around their chosen tailpipe exit.

The 2.5-inch tubing assortment includes over-the-axle pipes and optional tailpipe exits, so builders can shape the rear routing around the vehicle’s layout. Front adapter pipes, an intermediate pipe, and an H-pipe provide additional sections for connecting a custom system. Slip-fit connectors support assembly by letting sections join without a listed welding requirement. The product is explicitly described as pipes only, however, so mufflers and other installation hardware are not part of the stated package.

Skip it if you want 2.25-inch tubing for your build; Flowmaster 15935 U-Fit supplies the smaller stated diameter in a 16-piece pipe kit.

Flowmaster 15936 suits a fabricator planning a 2.5-inch dual system with over-axle routing and flexible tailpipe exits. It is a pipes-only foundation, so choose it only if you can supply the mufflers and remaining hardware.

#2 · Best 2.25-Inch Kit

2. Flowmaster 15935 U-Fit

• Material: Plastic
• Material Type: Plastic
• Installation Type: Bolt-On

Best for: Builders needing 2.25-inch tubing.

Why it ranks #2: This universal 16-piece U-Fit set offers 2.25-inch mandrel-bent, 16-gauge aluminized steel tubing and slip-fit connectors, but pipes only.

A stated 2.25-inch diameter distinguishes Flowmaster’s 16-piece U-Fit dual tubing kit for builders whose exhaust layout calls for smaller tubing than the brand’s 2.50-inch version. Its mandrel-bent, 16-gauge aluminized steel sections include over-axle pipes and optional tailpipe exits for custom routing.

The assortment includes front adapter pipes, an intermediate pipe, and an H-pipe, giving a fabricator multiple connection sections to work into a dual-exhaust layout. Slip-fit connectors can simplify positioning and joining during assembly, while over-the-axle pipes and optional tailpipe exits address rear routing choices. The 2.25-inch diameter is the key sizing distinction, and the kit is identified as pipes only. Plan to source mufflers and any additional mounting hardware needed for your particular installation separately.

Skip it if you need 2.5-inch tubing for your layout; Flowmaster 15936 U-Fit provides the larger stated diameter in a similar 16-piece pipes-only assortment.

Flowmaster 15935 is for fabricators whose custom dual system calls for 2.25-inch tubing and several connection sections. Its pipes-only format leaves mufflers and installation hardware to the builder, so account for those separately.

#3 · Best Silverado Fit

3. Colt Exhaust Silverado Kit

• Material: Stainless Steel
• Material Type: Stainless Steel

Best for: Silverado owners seeking hardware.

Why it ranks #3: The stainless-steel dual-pipe kit targets 1987–2002 Chevy Silverado 1500 applications and includes clamps and hangers for a more complete package.

Free clamps and hangers give the Colt Exhaust dual-pipe kit a practical installation advantage for owners of 1987–2002 Chevy Silverado 1500 trucks. Its stainless-steel construction and broad universal-fit description target a replacement or upgrade setup, while the included mounting pieces reduce the need to source those items separately.

The listing identifies this as a dual-pipe exhaust kit for 1987–2002 Chevy Silverado 1500 applications and calls the fit universal across a range of exhaust setups. That combination makes it relevant to Silverado owners considering a system change, but the supplied information does not specify pipe diameter or a detailed installation layout. Stainless steel is identified for corrosion resistance and durability, while included clamps and hangers provide mounting hardware. Verify the exact configuration against your truck before ordering.

Skip it if you need a stated 2.5-inch pipe size and muffler in the package; Truck Exhaust Kits ShopLine lists both its pipe size and included Flowmaster muffler.

This Colt kit is a candidate for Silverado 1500 owners within the listed 1987–2002 range who want stainless construction and included mounting hardware. The listing leaves pipe diameter unspecified, so that detail matters before purchase.

#4 · Best Bend Assortment

4. DNA Motoring ZTL-25SS

• Material: Stainless Steel
• Material Type: Stainless Steel
• Installation Type: Bolt-On

Best for: Custom fabrication builders.

Why it ranks #4: Its 16 stainless-steel pieces include four straight pipes plus 45-, 90-, and 180-degree bends, all with 2.5-inch outside diameter.

Four pipe shapes in one 16-piece stainless-steel set give custom exhaust builders a broad starting layout. The assortment includes 48-inch straight sections plus 45-, 90-, and 180-degree bends, enabling a fabricated route to take shape without relying on a single bend angle or straight-pipe format.

The 2.5-inch outside-diameter tubing uses slip-fit joints, which can make arranging and joining sections more straightforward during fabrication. Four 48-inch straights provide long runs, while the four 45-degree, four 90-degree, and four U-bend sections offer options for routing around obstacles. Stainless steel and computerized mandrel bends are specified for strength, durability, and smoother exhaust flow. This is a tubing assortment for a DIY build, not a complete muffler-and-hardware package.

Skip it if you want a ready-to-install truck system with a muffler and hardware; Truck Exhaust Kits ShopLine includes a Flowmaster muffler, clamps, and hangers.

Choose this DNA MOTORING set if you are fabricating a custom 2.5-inch route and want several bend options in stainless steel. It suits hands-on builders; plan separately for mufflers and mounting hardware.

5. Generic 15936 U-Fit

• Material: Plastic
• Material Type: Plastic
• Installation Type: Bolt-On

Best for: 2.5-inch pipe-kit shoppers.

Why it ranks #5: The listing identifies a 2.5-inch, 16-piece U-Fit pipe kit, but its generic branding and plastic material specification make verification especially important.

A 16-piece, 2.50-inch U-Fit dual exhaust pipe kit is the central specification offered under this generic listing, which identifies part number 15936. That gives shoppers a concrete size and kit format to compare when sourcing a pipe-only custom layout, while making careful identity and application checks especially important.

The listing describes a 2.50-inch, 16-piece U-Fit dual exhaust kit and identifies model and part number 15936. Those details can help a buyer compare the intended pipe size and kit identity with a planned build. However, the supplied listing does not detail the individual pipe shapes, connection pieces, or included installation hardware; it calls for checking fitment, dimensions, configuration, and mounting requirements. Treat it as a pipe-kit listing, not as confirmation of a complete muffler-and-hardware package.

Skip it if you need the specific pipe shapes and slip-fit connectors listed; Flowmaster 15936 U-Fit details over-axle pipes, adapters, an H-pipe, and connectors.

This listing may suit a shopper comparing a 2.50-inch, 16-piece pipe kit by part number. Its generic description leaves section contents and hardware unclear, so buyers needing a documented layout should prefer a more detailed listing.

6. ShopLine Dual Exhaust System

• Material: Alloy Steel
• Material Type: Alloy Steel
• Installation Type: Clamp-On

Best for: Ford truck clamp-on installers.

Why it ranks #6: This truck-oriented 2.5-inch system includes a Flowmaster muffler, clamps, hangers, and multi-piece tailpipes, but fitment is restricted to specified trucks.

A clamp-on dual system with installation hardware included lets qualifying Ford F-Series owners avoid a welding requirement. The ShopLine kit supplies a Flowmaster muffler, multi-piece tailpipes, clamps, and hangers, making it a more complete package than a pipes-only assortment for the specific truck configurations it supports.

The included clamps and hangers support the listed clamp-on installation approach, while the Flowmaster muffler and multi-piece tailpipes provide key system components in the package. Its 2.5-inch aluminized pipe is specified for trucks, but fit is restricted: the verified information says it fits Ford F-Series trucks without a factory dual-inlet muffler. Trucks lacking a 3-inch muffler inlet pipe need an adapter sourced separately. It is intended to retain emissions-control devices, not interfere with them.

Skip it if you have a factory dual-inlet muffler; Magnum Exhaust DK113-NT is a tailpipe-only truck kit rather than this restricted ShopLine application.

This ShopLine system fits Ford F-Series owners seeking a clamp-on package with a muffler and mounting hardware. Check the factory muffler configuration and inlet size; a truck without a 3-inch inlet needs a separate adapter.

7. Truck Exhaust Kits DIY System

• Material: Aluminum
• Material Type: Aluminum

Best for: Pickup owners converting to dual.

Why it ranks #7: The kit converts a single system to dual tailpipes and includes a two-chamber muffler, but its description targets late-model pickup trucks.

A two-chamber muffler and dual tailpipes give this Truck Exhaust Kits system the core components for converting a late-model pickup from single exhaust to dual. The 2.5-inch mandrel-bent, aluminized pipe is specified for longer life, and the listing says most jobs take an afternoon with basic hand tools.

The kit is described for late-model pickup trucks and supports all wheelbases, with 4- or 6-cylinder applications stated in the listing. Its two-chamber performance muffler and dual tailpipes make it a conversion-oriented package rather than a pipes-only assortment. Two- and three-piece tailpipes are noted for easier installation, while the 2.5-inch inlet connection size helps define the system interface. The stated installation estimate is most jobs in one afternoon using basic hand tools, not a guarantee for every truck.

Skip it if you need only custom pipe sections without a muffler; Flowmaster 15936 U-Fit is a 16-piece, 2.5-inch pipes-only alternative.

This Truck Exhaust Kits system suits late-model pickup owners converting from single to dual exhaust who want a muffler and tailpipes together. Its stated truck, wheelbase, and cylinder coverage still warrants application-specific checking.

#8

8. Magnum Tailpipe-Only Kit

• Material: Aluminum
• Material Type: Aluminum
• Installation Type: Clamp-On

Best for: Truck tailpipe replacement projects.

Why it ranks #8: Two 2.5-inch mandrel-bent tailpipes come with insulated hangers and muffler clamps, but this is a tailpipe-only truck kit without tips.

Two cut-and-swaged, 2.5-inch mandrel-bent tailpipes make this Magnum Exhaust kit a focused choice for truck builds that need rear sections rather than a full exhaust package. Multi-depth insulated hangers and muffler clamps are included, helping support mounting across different installation depths.

The kit centers on two 2.5-inch tailpipes, cut and swaged for a tailpipe-only installation, so it can suit a project where the rest of the exhaust system is already addressed. Multi-depth insulated hangers provide mounting options, and muffler clamps are included to secure the assembly. The listing identifies a truck application and clamp-on installation, but does not specify a muffler or exhaust tips among the supplied components. Its aluminum material listing is also worth noting when comparing materials.

Skip it if you need a muffler and dual tailpipes in one package; Truck Exhaust Kits DIY Dual System includes a two-chamber muffler and dual tailpipes.

Choose Magnum Exhaust DK113-NT for a truck project focused on replacing or adding tailpipes while reusing other exhaust components. It includes hangers and clamps, but its no-tip, tailpipe-only scope is a firm boundary.

#9

9. Magnum Flowmaster 40 Kit

• Material: Stainless Steel
• Material Type: Stainless Steel

Best for: Truck owners wanting a Flowmaster 40.

Why it ranks #9: It combines a Flowmaster 40 Series muffler with two 2.5-inch tailpipes, but the listing describes a truck kit rather than a universal pipe assortment.

A Flowmaster 40 Series muffler paired with dual 2.5-inch mandrel-bent tailpipes makes this Magnum Exhaust kit a truck-focused package for buyers seeking both a named muffler and rear pipes. Multi-depth insulated hangers and muffler clamps add mounting hardware, while the no-tips title keeps the package scope clear.

The listing specifies a single 3-inch inlet and dual 2.5-inch outlets for the Flowmaster 40 Series muffler, helping buyers understand the system’s transition from a single inlet to dual tailpipes. The two tailpipes are mandrel-bent, cut, and swaged, and the kit includes multi-depth insulated hangers and muffler clamps for installation. It is identified for trucks and uses stainless steel. Exhaust tips are not included, so the finished appearance depends on separately chosen tailpipe ends.

Skip it if you only need tailpipes and want to omit a muffler; Magnum Exhaust DK113-NT lists two 2.5-inch tailpipes with hangers and clamps.

This kit suits truck owners wanting a Flowmaster 40 muffler and dual tailpipes together, with hangers and clamps supplied. It is not a tip-inclusive package, and the listed 3-inch inlet and 2.5-inch outlets define its configuration.

#10

10. Colt Exhaust Silverado 3500 Kit

Best for: Silverado owners wanting black tips.

Why it ranks #10: This stainless-steel dual-pipe kit includes black-coated tips, clamps, and hangers, but its stated compatibility is limited to 1988–2018 Chevy Silverado 3500.

Two black-coated tips distinguish this stainless-steel Colt Exhaust dual-pipe kit for 1988–2018 Chevy Silverado 3500 owners seeking a finished rear appearance alongside the exhaust upgrade. Free clamps and hangers are included, and the listing describes a mandrel dual-pipe setup with an emphasis on exhaust flow.

The listed 1988–2018 Chevy Silverado 3500 compatibility narrows this kit to a specific truck application, while stainless-steel construction is identified for durability and corrosion resistance. Its two black-coated tips supply a finished exit detail, and free clamps and hangers provide mounting pieces. The description also presents reduced backpressure and improved exhaust flow as intended benefits. It does not state the pipe diameter in the supplied details, so buyers should treat sizing as an unresolved fit consideration.

Skip it if you need a stated pipe diameter before choosing; Colt Exhaust 918100+919100 for Silverado 1500 applications also leaves diameter unspecified, so seek a listing with explicit sizing.

This Colt kit suits Silverado 3500 owners in the listed year range who want stainless dual piping, black-coated tips, and mounting hardware. The unstated diameter remains a key boundary for confirming a compatible setup.
