Description BORLA 140997BC Cat-Back Exhaust System 2.75" ATAK (3.5" Black Chrome Tips) for CHEVROLET Silverado 1500 2024 / GMC Sierra 1500 2024

This system is designed for factory split rear exit vehicles, excluding ZR2 and AT4X models. For Crew Cab with Standard Bed (6' 7") and 157" wheelbase vehicles, Adapter 60706 is required. The system includes a valve simulator to prevent the check engine light from activating.

The 3.5" into dual 2.75" exhaust features the aggressive ATAK muffler and Polyphonic Harmonizer Technology, which uses patented units with pipes of varying diameters and lengths to create harmonized exhaust notes for a clean, full-bodied sound without interior drone. The Polyphonic Harmonizer behind the muffler can be replaced with muffler 60679 for a quieter S-Type sound level. Dual 3.5" round black chrome on T-304 stainless steel tips are featured on each tail pipe, and installation requires removal of the factory valance tips.
