Borla's Cat-Back exhaust system features 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, respected by motoring enthusiasts everywhere.
Each system is built from premium 300-series austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, Borla stands behind every system with a Million-Mile Warranty.
*This system includes active exhaust valve simulators and is recommended for cars with significant modifications. The active exhaust valves in the stock exhaust have been removed, valve simulator mounts on the outside of the pipe allow the stock valve motors to be re-attached to prevent an error code.*
