Borla Performance ATAK Polyphonic Harmonizer Upgrade Kit - 2019-2026 Silverado/Sierra 1500 6.2L V8 (60680)
Unleash the full acoustic power of your half-ton truck and elevate your driving experience with the Borla Performance ATAK Polyphonic Harmonizer Upgrade Kit for the 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 6.2L V8. This premium modular sound-changing component is engineered specifically for truck owners who want to step up to an aggressive, high-volume performance profile without replacing their entire performance architecture. Designed as a direct-fit acoustic swap, this assembly allows you to replace the small secondary rear muffler found within a Borla S-Type setup, effectively converting your configuration into a loud, high-velocity ATAK volume profile.
This system features Borla's patented Polyphonic Harmonizer Technology, utilizing specialized internal piping configurations of varying diameters and precise lengths to blend multiple exhaust notes into a clean, rich, and full-bodied performance roar. Built to handle heavy-duty hauling, track-day abuse, and severe weather, this high-performance component is manufactured from premium T-304 austenitic stainless steel for ultimate protection against structural rust and trail corrosion. Precision computer numerical control (CNC) manufacturing processes ensure accurate alignment beneath the truck frame rails, while its free-flowing 3.5-inch diameter architecture preserves optimized exhaust gas velocity and maximum engine power. This product is backed by Borla's legendary lifetime Million-Mile Warranty.
