BORLA – ATAK Cat-Back Exhaust System

Description

The BORLA ATAK Cat-Back #140998 is designed for the Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the V8 6.2L engine. The 3.5 in. into dual 2.75 in. system features BORLA's aggressive ATAK muffler and Polyphonic Harmonizer Technology for a rich, full-bodied sound with no drone inside the cabin. The dual 3.5 in. × 3.28 in. bright chrome on T-304 stainless steel tips (two per tail pipe) are included; installation requires removal of factory valance tips. A valve simulator prevents Check Engine Light activation. Muffler 60679 can replace the Polyphonic Harmonizer to reach the S-Type sound level. Compatible with factory split rear exit vehicles only. Add adapter 60706 for Crew Cab with Standard Bed (6' 7"). Excludes ZR2 and AT4X models.
