73-78 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 have designed a line of direct fit 74-78 oval mufflers so you don't have to live with your mufflers "ridin'low". We call these "Hideaway."1974-1978 2 1/2 hide-away Magnaflow muffler1968-1974 2 1/2 4 speed intermediate pipe1966-1974 2-2 1/2 front exhaust pipeMagnaFlow's Wide Open Performance Mufflers outflow OEM chamber style mufflers by as much as 167 percent. This reduces engine heat and backpressure and improves exhaust scavenging from the combustion chamber. MagnaFlow minimizes the power robbing effects of the OEM system to restore torque and horsepower to the engine.
