This 2.5" diameter dual Cat-Back™ system contains a Merge X-Pipe for increased performance and improved sound. The system features the aggressive ATAK® sound with no drone inside the vehicle. The exhaust exits thru single 4" round bright chrome on T-304 stainless steel tips on each muffler assembly. A system with black chrome on T-304 stainless steel tips is also available. Optional front muffler 60561 can be added to replace the Merge X-Pipe for addtional sound control. BORLA® Cat-Back™ and Axle-Back multi-core technology is 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.
Each system is built from premium T-304 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 numerical control (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.
