This True Dual Borla Cat-Back system was designed specifically for the Q50. It features a merge X-Pipe 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. 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 classic S-Type sound level delivers a sporty sound and a deeper tone without any drone inside the cabin. The system has a single 4.5 in. carbon fiber with black anodized center tip on each tail pipe. Borla Cat-Back and 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. Ultra-smooth mandrel bends ensure maximum a flow and power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
