This BORLA system has a valve simulator to prevent the Check Engine Light from coming on. Optional True Dual Cat-Back system available. The 3.5" into dual 2.75" system features BORLA 's classic S-Type sound 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 muffler behind the primary muffler in this BORLA S-Type system with Polyphonic Harmonizer 60680 to attain the ATAK sound level (louder than S-Type). This system features dual 3.5" X 3.28" bright chrome on T-304 stainless steel tips on each tail pipe. Installation REQUIRES removal of the Factory Valance Tips. Systems with black chrome on T-304 stainless steel tips, carbon fiber tips, and systems that reuse the original equipment tips are also available.

Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere.
