Borla ATAK 3.5" to Dual 2.75" Catback Exhaust System with Black Chrome Tips - 2024-2026 Silverado/Sierra 1500 6.2L V8 (140997BC)
Unleash the full acoustic potential and performance of your half-ton truck with the Borla ATAK Catback Exhaust System. Purpose-built for the 2024-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 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 V8 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 truck's original equipment, utilizing an integrated mechanical valve simulator to preserve factory computer parameters and prevent any 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. Moving past the rear fascia, the system terminates in an aggressive dual split rear configuration with premium dual 3.5-inch round black chrome tips on each tailpipe path. Every connection is CNC manufactured for a secure, factory-style direct-fit replacement, backed by Borla's comprehensive lifetime Million-Mile Warranty.
