This 2.5" diameter True Dual BORLA® Cat-Back™ system was designed specifically for the Q50. It features an internal H-Pipe inside the front muffler and BORLA®'s patented Polyphonic Harmonizer technology for increased performance and improved sound. BORLA®'S Polyphonic Harmonizer Technology 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. The ATAK® sound level delivers an aggressive, head-turning sound with no drone inside the cabin. The rear section of this exhaust system incorporates Borla's patented SwitchFire™ design. Completely eliminating the turbulent center intersection of a standard X-Pipe, BORLA®'S patented SwitchFire™ design truly blends the combustion pulses from both sides of the engine for improved performance and a custom sound. The exhaust exits thru single 4.5" round bright chrome on T-304 stainless steel tip on each tail pipe. Systems with black chrome on T-304 stainless steel tips and carbon fiber tips are also available. 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, high-quality 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 a 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.
