Proform Exhaust & Performance

Proform exhaust and performance parts on this page are engine-bay accessories more than complete systems. The range is split between air intake, fuel system and exhaust system items.

Air intake and fuel system parts are mostly for carburetors: a metering block, a vacuum secondary diaphragm, studs with lock washers and nuts, a return spring bracket for Ford applications, and special tools. The tools include a carburetor jet installation tool, a float adjusting tool and a power valve removal tool. These help you rebuild or tune a carburetor.

Exhaust items are wedge-locking header bolts in hex head, in black oxide or nickel plated finishes and in different lengths, including sets for the LS engine. Header bolts hold the exhaust header to the cylinder head, and the wedge-locking design resists loosening.

The vehicle list is mostly Chevrolet: Chevrolet Camaro, Chevrolet Corvette, and C and K series pickups and Suburbans. To choose, work from what you are building. Match the carburetor part to the carburetor family named in the title, and match header bolts to the thread and length.

Each product page lists the years, makes and models it fits, and the vehicle selector shows only parts for your vehicle. For other brands, see the full exhaust and performance range.
