Borla Performance ATAK Cat-Back Exhaust System - 2022-2023 Silverado ZR2 & Sierra AT4X 6.2L V8 (140915)
Unleash the ultimate high-volume acoustic roar and optimized underbody clearance on your flagship off-road truck with the Borla Performance ATAK Cat-Back Exhaust System for 2022-2023 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X models equipped with the 6.2L V8 engine. Purpose-built to clear tight suspension setups and rugged trail terrain, this high-performance exhaust configuration utilizes specialized dual 2.75-inch turn-down tailpipes that dump discreetly beneath the chassis, maximizing your rear departure angle during demanding rock crawling or trail navigation. Featuring Borla's highest-volume ATAK (Acoustically Tuned Applied Kinetics) sound profile along with patented Polyphonic Harmonizer Technology, this system delivers an aggressive, full-bodied exhaust note that harmonizes multiple acoustic notes while completely eliminating interior cabin drone during highway cruising.
Engineered to maximize exhaust gas velocity and unlock hidden horsepower, the assembly relies on patented straight-through, multi-core technology and ultra-smooth mandrel bending to minimize backpressure and optimize fuel economy. For owners who eventually want to tone down the track-side presence, the modular layout allows you to replace the primary Polyphonic Harmonizer unit with Borla's optional secondary muffler (Part Number 60679) to easily attain the quieter S-Type sound level. The complete kit is manufactured from top-tier T-304 austenitic stainless steel, providing superior long-term protection against structural oxidation, rust, and road salt degradation. A massive 3.5-inch single mid-pipe splits cleanly into dual 2.75-inch tailpipes, and precision computer numerical control (CNC) manufacturing guarantees an accurate, worry-free bolt-on fitment. This premium truck exhaust system is proudly made in the USA and backed by Borla's legendary lifetime Million-Mile Warranty.
