Enjoy the small-block in your C3
A classic Corvette is as much about the V8 as its shape. Kooks 21302200 gives your small-block C3 exhaust a purpose-made front section, with 1-3/4-inch 304 stainless primaries and 3-inch collectors.
SKU: 21302200
Choose around the engine in your Corvette
The application is the 1968-1982 C3 with a small-block Chevrolet engine. The fitment table keeps the original vehicle identities visible, with the installed-small-block requirement where the car originally had a different engine.
Match the connecting exhaust
Use the 3-inch collector diameter when planning the rest of your exhaust. Your installer should check the actual engine position and nearby chassis components on your car before final alignment.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.
Matching products
For the same 1968-1982 C3 small-block installation, compare the 1-7/8-inch C3 headers if your engine and connecting exhaust call for that primary size.
