Description

This BORLA Cat-Back system has a valve simulator to prevent the Check Engine Light from coming on. It was designed specifically for the 6.2L Silverado 1500 ZR2 and Sierra 1500 AT4X. The 3.5″ diameter system has dual 2.75″ turn down tail pipes and features the classic BORLA S-Type sound with no drone inside the vehicle. Replace the small muffler behind the primary muffler in the “S-Type” system with Polyphonic Harmonizer 60680 to attain the “ATAK” sound level (louder than “S-Type”). Optional “True Dual” Cat-Back system available. BORLA Cat-Back &amp
