This Cat-Back system re-uses the factory tips and does NOT include tips. Optional BORLA tips can be purchased separately. The system was designed specifically for the 3.3L Stinger GT with a True Dual configuration that is 2.25 in. diameter into the mufflers, with dual 2.25 in. out of the mufflers. It contains a M erge X-Pipe for increased performance and improved sound. The system features BORLA'S Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the mufflers. The mufflers then enhance this sound to the character and volume appropriate for this S-Type system. Like all BORLA Cat-Back and Axle Back systems, there is no drone inside the vehicle. The mufflers have dual 2.25 in. outlets. The exhaust exits through the Original Equipment (O.E.) valance. Tips NOT included, reuse O.E. valance. BORLA Cat-Back & 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, 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.
