Borla ATAK 3.5" to Dual 2.75" Catback Exhaust System with Turndown Tips - 2024-2026 Silverado ZR2 / Sierra AT4X 6.2L V8 (141004)
Enhance the exhaust note and off-road clearance of your premium overland truck with the Borla ATAK Catback Exhaust System. Purpose-built for the 2024-2026 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X equipped with the 6.2L V8 engine, this system delivers Borla's most aggressive ATAK sound profile. It provides a high-volume, muscular, and race-inspired roar under acceleration while maintaining a completely comfortable, drone-free environment inside the cabin during daily driving. This premium exhaust configuration is engineered to integrate seamlessly with your vehicle's complex onboard systems, utilizing an integrated mechanical valve simulator to preserve factory computer parameters and prevent unwanted check engine lights.
Constructed entirely from premium, high-grade T-304 austenitic stainless steel, this exhaust system delivers long-term durability and structural protection that leaves lower-tier T-400 series alternatives far behind. The high-flow design begins with a single 3.5-inch mid-pipe that branches out into ultra-smooth, mandrel-bent dual 2.75-inch tailpipes, reducing backpressure to maximize gas velocity and unlock hidden horsepower. Engineered specifically with high-clearance off-roading in mind, the system terminates in hidden dual turndown tailpipes that dump before the rear bumper fascia, protecting your exhaust paths from rocks and rough terrain obstacles. Every connection is CNC manufactured for a secure, factory-style direct-fit replacement, backed by Borla's comprehensive lifetime Million-Mile Warranty.
