C4 Corvette

C4 Corvette

We set the pace for stainless steel exhaust systems, especially when it comes to Corvette exhaust systems. All of our Corvette exhaust systems are built by hand using T304 stainless steel. Through extensive dyno testing we concluded that the LT motors love to breathe, so we designed the entire system using 3" mandrel bent tubing. With a uniquely designed resonator and muffler pair, your LT1, LT4, and ZR1 motor will increase in performance and sound.

This direct bolt-on replacement system adds increased performance at 25 horsepower, improved sound quality, and precision built quad tips for a stylish finish.
