ABOUT THIS PRODUCT

This BORLA system has a valve simulator to prevent the Check Engine Light from coming on. The 3.5 Inch into dual 2.75 Inch system features BORLA's aggressive ATAK muffler and 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 with no drone inside the vehicle. Replace the Polyphonic Harmonizer behind the muffler in this ATAK system with muffler 60679 to attain the S-Type sound level (quieter than ATAK). Tips NOT Included, reuse factory tips.
