    All engines

Designed for compatible 1973–1974 Chevrolet and GMC 2WD C/K pickups, including C10 applications. Intended for compatible small-block Chevrolet 265–400 engine configurations. Verify the truck uses the correct exhaust manifold outlet orientation before ordering. Not suitable for stock manifolds that exit straight downward. Confirm 2WD drivetrain, as 4WD chassis routing and clearances can differ. Check wheelbase, cab style, bed length, transmission crossmember, and rear suspension clearance. Modified engines, headers, relocated fuel tanks, lowered suspension, or custom drivetrain components may require fabrication. Some installations may require trimming, welding, clamps, hangers, adapters, or other exhaust hardware. Mufflers and installation hardware should be verified against the exact Hooker kit contents before purchase. Always confirm the manufacturer part number and application guide for final fitment.

005Counter questions

Asked about this part

Hooker Manifold Back Exhaust System for 73-74 GM C10
It is designed for compatible 1973–1974 Chevrolet and GMC 2WD C/K pickups, including applicable C10 models.
Will it fit a 1973 Chevrolet C10?
Yes, provided your truck matches the required 2WD, engine, manifold outlet, and chassis configuration.
Will it fit a 1974 Chevrolet C10?
Yes, for compatible 1974 C10 applications with the correct exhaust manifold and underbody layout.
Is this system for 2WD or 4WD trucks?
It is intended for compatible 2WD trucks. Four-wheel-drive models use different chassis and exhaust routing and should not be assumed to fit.
What size exhaust tubing does it use?
The system uses 2.25-inch tubing.
Is the tubing mandrel bent?
Yes. Mandrel bends help maintain a more consistent internal diameter through curves for smoother exhaust flow.
What material is the exhaust system made from?
It uses aluminized steel tubing for a practical combination of strength, durability, and corrosion resistance.
What does “manifold-back” mean?
Manifold-back means the exhaust system begins downstream of the engine’s exhaust manifolds and replaces much of the piping toward the rear of the truck.
Does it connect directly to the factory manifolds?
It is designed for compatible manifold configurations, but the exact outlet style must be checked before ordering.
Will it fit stock manifolds that exit straight down?
No. This system is not intended for stock manifolds with straight-down outlets.
Will this work with headers?
Possibly, but headers can change the collector position and outlet size. Adapters or custom fabrication may be required.
What engines is this system intended for?
It is intended for compatible small-block Chevrolet applications, including certain 265–400 cubic-inch engine configurations.
Does this system include mufflers?
Muffler inclusion should be verified against the exact Hooker part number and supplier listing before purchase.
Are clamps and hangers included?
Some hardware may be supplied depending on the exact kit, but clamps, hangers, and installation hardware should be confirmed before ordering.
Where does the exhaust exit?
The system is designed for a side exit behind the rear tires on compatible trucks.
Is it a dual-exhaust system?
It is intended as a dual-exhaust configuration for compatible applications.
Will it improve exhaust flow?
The mandrel-bent 2.25-inch tubing can help reduce restriction compared with old, crushed, leaking, or heavily corroded exhaust pipes.
Will this exhaust system make my truck louder?
Exhaust sound depends heavily on the mufflers, engine, camshaft, compression, and other exhaust components. The piping itself can contribute to a more performance-oriented tone.
Is this good for a restoration project?
Yes. It is a strong option for owners restoring a 1973–1974 GM C10 who want pre-formed exhaust routing with a classic side-exit appearance.
Is welding required?
Welding may be required depending on the rest of the exhaust system. Some installations can use clamps, while others benefit from welded joints.
Will I need to trim any pipes?
Minor trimming or adjustment may be necessary depending on wheelbase, cab configuration, bed length, existing components, and previous modifications.
Will it fit a lowered C10?
Possibly, but lowered suspension changes axle and frame clearance. Carefully check tailpipe and rear suspension clearance before installation.
Will it fit a truck with a relocated fuel tank?
Not necessarily. Fuel tank relocation can interfere with factory-style exhaust routing and may require custom fabrication.
Can I install this system at home?
Experienced DIY owners with proper lifting equipment and exhaust tools may be able to install it. Professional installation is recommended if cutting, welding, or fitment modification is required.
Does the system fit long-bed and short-bed trucks?
Fitment can depend on wheelbase and bed configuration. Confirm the exact Hooker application before assuming compatibility.
Is this a universal exhaust system?
No. It is application-focused for compatible 1973–1974 GM 2WD C/K trucks rather than being a generic universal pipe kit.
What should I check before buying?
Verify the truck’s year, Chevrolet or GMC model, 2WD drivetrain, engine, exhaust manifold outlet direction, wheelbase, cab and bed configuration, existing exhaust layout, suspension clearance, and any fuel-tank modifications.
Is this suitable for performance use?
Yes. The mandrel-bent tubing and freer-flowing layout make it suitable for street-performance and mild performance builds when paired with the correct engine and muffler setup.
What if my truck has already been modified?
Headers, transmission swaps, lowered suspension, custom crossmembers, relocated fuel tanks, or previous exhaust work may affect fitment and could require additional fabrication.
Why choose a pre-bent Hooker system instead of a custom exhaust?
A pre-bent application-specific system reduces the amount of fabrication required and provides a cleaner starting point for routing the exhaust under a compatible classic C10.
