BORLA Cat-Back™ exhausts 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.

Each system is built from premium Aircraft-Quality T-304 Stainless Steel, an alloy superior to T-400 series knockoffs, to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Choose from two versions: 'Touring' and a slightly more aggressive 'Sport' version. Get the Touring version if you just want a slightly deeper tone over stock with a mild cruising sound. The 'sport' version offers slightly more volume for those wanting a more 'sporting' sound.

The Borla system installs 'downstream' from the secondary catalytic converter. This requires cutting of the stock system just behind the cat, where the Borla system is attached. The rest bolts right-in.
