Product Details

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).

No A.I.R. Provisions.

System Includes:

  • 1974-1979 2" Oval "hideaway" Muffler
  • 1968-1974 SB 4 Speed Front Exhaust Pipe
  • 1969-1974 2" 4 Speed Intermediate Exhaust Pipe

Hangers not included.
