BORLA – ATAK Cat-Back Exhaust System
Description
The BORLA ATAK Cat-Back #140996 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, utilizing patented units containing pipes of different diameters and lengths to create multiple exhaust notes that harmonize for a clean, rich, full-bodied sound with no drone inside the cabin. A valve simulator prevents Check Engine Light activation. Factory tips are reused (not included); systems with tips are available separately. Muffler 60679 can replace the Polyphonic Harmonizer to reach the S-Type sound level. Compatible with factory split rear exit vehicles only. Excludes ZR2 and AT4X models.
