This 2.5" diameter True Dual Borla(r) Cat-Back(tm) system features an internal H-Pipe inside the front muffler and Borla(r)'s patented Polyphonic Harmonizer technology for increased performance and improved sound. Borla(r)'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(r) sound level delivers an aggressive, head-turning sound without any drone inside the cabin. The rear section of this exhaust system incorporates Borla(r)'s patented SwitchFire(r) design, and a single 4.5" round carbon fiber with black anodized center tip on each tail pipe. Completely eliminating the turbulent center intersection of a standard X-Pipe, Borla(r)'s patented SwitchFire(r) design truly blends the combustion pulses from both sides of the engine for improved performance and a custom sound. Systems with bright chrome on T-304 stainless steel tips and black chrome on T-304 stainless steel tips are also available. Borla(r) Cat-Back(tm) & 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(r) 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(r) stands behind every system with a Million-Mile Warranty. Just what you'd expect from the worlds most experienced (and most winning) exhaust brand.
