Borla cat-back exhaust system.

EXCEPT Convertible. Do not use the adapters for full 3” inlets. This system is designed for use on cars WITHOUT the Active Exhaust feature. Muffler contains Polyphonic Harmonizer technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. BORLA® Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed 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. 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.
