The Borla 60739 is a 2.5 in optional mid-section designed to work only with Borla axle-back systems 11981 and 11981BC. Installation requires cutting the mid-section of the stock exhaust behind the catalytic converters and welding the 60739 inlet pipes to the rear of the catalytic converters. It features a Merge X-pipe for increased performance and improved sound, and it raises overall volume while keeping the S-Type tone of the 11981 and 11981BC. Combined with the axle-back, it creates a complete cat-back system. Because it mounts behind the factory catalytic converters, it retains the cats and is 50-state emissions legal. Built from premium T-304 stainless steel with ultra-smooth mandrel bends and precision CNC manufacturing. It is made in the USA and backed by the Borla Million-Mile Warranty.
