The Borla ATAK (Aggressive Tongue-and-Cheek) Cat-Back exhaust system is designed for truck owners who demand a high-volume, performance-oriented sound without the annoyance of interior drone. This system (MPN: 140997BC) is constructed from premium T-304 stainless steel and features Borla's patented Polyphonic Harmonizer Technology. By utilizing piping of different diameters and lengths that harmonize together, Borla delivers a clean, rich, full-bodied note. To ensure seamless operation with factory electronics, this system includes a valve simulator to prevent Check Engine Lights (CEL) related to exhaust valve actuators.
