Borla Performance S-Type Rear Muffler Upgrade Kit - 2019-2026 Silverado/Sierra 1500 6.2L V8 (60679)
Fine-tune the exhaust note of your half-ton truck and bring an added layer of acoustic refinement to your drive with the Borla Performance S-Type Rear Muffler Upgrade Kit for the 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 6.2L V8. This premium modular sound-changing solution is specifically developed for truck owners who want to scale back their exhaust volume without altering their entire performance architecture. Engineered as a direct acoustic swap, this component allows you to replace the un-resonated Polyphonic Harmonizer section located behind the main muffler in an existing Borla ATAK system, effectively converting your system into a deeper, more balanced S-Type volume profile.
Built to withstand demanding payload towing, high-temperature exhaust flow, and daily highway use, this heavy-duty rear muffler assembly is manufactured from high-quality T-304 austenitic stainless steel for structural protection against rust, weather, and trail corrosion. Precision computer numerical control (CNC) manufacturing processes ensure accurate alignment beneath the truck's frame rails, while its free-flowing 3.5-inch diameter architecture preserves optimized exhaust gas velocity and maximum engine power. This conversion kit integrates seamlessly into your existing Borla infrastructure and is backed by Borla's legendary lifetime Million-Mile Warranty.
