2019-2023 Chevrolet Silverado 1500/ 2019-2023 GMC Sierra 1500 Cat-Back Exhaust System ATAK Part # 140776BC

EXCEPT ZR2 & AT4X. Factory Split Rear Exit Vehicles ONLY. Add Adapter 60706 for Crew Cab with Standard Bed (6' 7") 157" Wheelbase vehicles. This 3.5" into dual 2.75" system features BORLA®'s aggressive ATAK® muffler and Polyphonic Harmonizer Technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound with no drone inside the vehicle. Replace the Polyphonic Harmonizer behind the muffler in this ATAK® system with muffler 60679 to attain the S-Type sound level (quieter than ATAK®). This system features dual 3.5" round black chrome on T-304 stainless steel tips on each tail pipe. Installation REQUIRES removal of the Factory Valance Tips. Systems with bright chrome on T-304 stainless steel tips, carbon fiber tips, and systems that resue the original equipment tips are also available. Installation REQUIRES removal of the Factory Valance Tips. Using BORLA® Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth.

BORLA® Cat-Back™ and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere.
