Borla S-Type Cat-Back Exhaust Systems
Borla’s S-Type Cat-Back Exhaust System 140677 contains a merge X-Pipe for increased performance and improved sound. The system is equipped with MDS (multi-displacement system) valve simulators which ELIMINATE the MDS valves. This avoids any warning lights on the dash while providing maximum flow at all times. Tips are NOT included; use factory valance / tips. Borla cat-back and 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. Each system is built from premium T-304 austenitic stainless steel to deliver the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power; and precision computer-controlled CNC manufacturing facilitates an accurate fit. Best of all, Borla stands behind every system—just what you’d expect from the world’s most experienced (and most winning) exhaust brand.
