Description BORLA 140997CFBA Cat-Back Exhaust System 2.75" ATAK (3.5" Carbon Fiber 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") 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 an 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 to achieve the quieter S-Type sound level. Dual 3.5" round carbon fiber tips with black anodized centers are featured on each tail pipe. Installation requires removal of the factory valance tips.
