Borla cat-back exhaust system.

This BORLA® system has a valve simulator to prevent the Check Engine Light from coming on. It features a True Dual design which is unique in the industry. Installation REQUIRES cutting the Original Equipment (O.E.) Y-Pipe. The muffler contains an internal X-Pipe for increased performance and improved sound. Give your ZR2 or AT4X the power, performace, and sound it deserves, bolt on a BORLA®. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

A cat-back system replaces everything behind the catalytic converter and leaves emissions equipment in place.
