1973-78 Corvettes from the factory had a round case muffler which can be seen below your rear valance or bumper. In 79-82 GM went back to an oval case muffler, similar to what was used in 63-72. This muffler tucked up under the car and was not visible under your bumper. We've applied this improved design to be used for 1975-78 Corvettes.
Exhaust system components are made from 14 gauge (.070) aluminized pipe.
For off road use only (no catalytic converter).
