Borla cat-back exhaust system.

This BORLA Cat-Back system has a valve simulator to prevent the Check Engine Light from coming on. Replace the small muffler behind the primary muffler in the "S-Type" system with Polyphonic Harmonizer 60680 to attain the "ATAK" sound level (louder than "S-Type"). Optional "True Dual" Cat-Back system available. BORLA Cat-Back & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Give your ZR2 or AT4X the 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.
