    All engines

Designed for compatible 1973–1987 Chevrolet and GMC C/K pickup trucks. Verify your exact model, drivetrain, wheelbase, cab style, and bed length before ordering. Intended for compatible 10, 15, 20, 1500, and 2500 truck applications. Confirm that your exhaust system uses 2.50-inch tubing. Check muffler location, inlet/outlet arrangement, and existing exhaust routing. Some trucks may require trimming, adapters, welding, clamps, or custom hangers for final installation. Vehicles with lowered suspension, relocated fuel tanks, aftermarket rear axles, or custom exhaust systems may require additional clearance checks. Tailpipe routing around the rear axle and differential should be verified against your specific chassis configuration. Exhaust tips, mufflers, hangers, and clamps may need to be purchased separately. Final compatibility should be confirmed using Flowmaster’s application information for the specific part number.

005Counter questions

Asked about this part

What vehicles do these Flowmaster pre-bent tailpipes fit?
They are intended for compatible 1973–1987 Chevrolet and GMC C/K pickups, including applicable 10, 15, 20, 1500, and 2500 models.
Will these tailpipes fit a Chevrolet C10?
Yes, for compatible 1973–1987 Chevrolet C10 applications using the correct exhaust layout and 2.50-inch tubing.
What is the pipe diameter?
The tailpipes use 2.50-inch exhaust tubing.
Are these tailpipes mandrel bent?
Yes. The pipes are designed with mandrel bends to help maintain a more consistent internal diameter through curved sections.
What material are the tailpipes made from?
They are made from aluminized steel, which provides a practical balance of durability and corrosion resistance for street-driven trucks.
Are both left and right tailpipes included?
Yes. The set is intended to include one left-side and one right-side tailpipe.
Are these for a dual-exhaust system?
Yes. The pair is designed for compatible dual-exhaust configurations.
Where do the tailpipes exit?
They are designed to route around the rear axle and exit near the rear wheel area on compatible trucks.
Will they fit a GMC C15?
They may fit compatible GMC C15 applications within the advertised year range. Verify your truck's exact chassis and exhaust configuration before ordering.
Do these tailpipes fit C20 and 2500 trucks?
Yes, for compatible C20, 20, and 2500 applications that match the required exhaust routing and pipe diameter.
Will these fit a 4WD K10 or K20?
Fitment depends on the exact chassis and exhaust layout. Four-wheel-drive applications should be confirmed separately using Flowmaster’s application guide.
Can I use these with factory exhaust manifolds?
Possibly. These are rear tailpipe sections, so compatibility depends more on the muffler location and downstream exhaust layout than the exhaust manifolds themselves.
Can I use these with headers?
Yes, if the rest of the exhaust system is configured to connect to 2.50-inch tailpipes. Additional pipes, reducers, or adapters may be required.
Are mufflers included?
No. These are tailpipes only. Mufflers should be purchased separately unless specifically included by the seller.
Are exhaust tips included?
Exhaust tips are not confirmed as part of the package and may need to be purchased separately.
Are clamps and hangers included?
Clamps, hangers, and additional hardware are not confirmed as included. Verify the package contents before installation.
Do these tailpipes require welding?
Welding may be required depending on the rest of the exhaust system. Some setups can use clamps, while others may need trimming and welding for a secure final fit.
Are these direct-fit tailpipes?
They are pre-bent for specific GM truck applications, which reduces fabrication work. Final installation may still require minor adjustments depending on the truck’s exact configuration.
Will the pipes fit a lowered truck?
Possibly, but lowered suspension can reduce clearance around the axle, frame, or exhaust. Check all underbody clearances before installation.
Will these fit a truck with a relocated fuel tank?
Not necessarily. Fuel tank modifications may interfere with the factory-style tailpipe route, so custom exhaust work may be required.
What are the benefits of pre-bent tailpipes?
Pre-bent pipes reduce the need to fabricate exhaust bends from scratch and help provide a cleaner route around the rear suspension and axle.
Do mandrel bends improve exhaust flow?
Mandrel bending helps preserve the pipe’s internal diameter through bends, which can support smoother airflow compared with heavily crushed bends.
Are these suitable for classic truck restoration?
Yes. They are a practical replacement for compatible square-body Chevrolet and GMC trucks undergoing exhaust restoration or dual-exhaust upgrades.
What should I verify before ordering?
Confirm your truck’s exact year, Chevrolet or GMC model, drivetrain, wheelbase, cab and bed configuration, muffler location, exhaust routing, rear suspension clearance, and 2.50-inch pipe size before purchasing.
