Borla ATAK Cat-Back exhaust system for the 2009-2021 Toyota Tundra 5.7L V8, built from premium austenitic T-304 stainless steel. This is a 2.25" true dual, split side-exit system with single 4" round black chrome tips on each tail pipe, and an internal H-pipe in the muffler for added performance and sound. ATAK is Borla’s loudest tier, delivering an aggressive V8 growl with no in-cabin drone, while mandrel bends and CNC fabrication keep the full dual system lighter than the factory single exhaust. Note: Borla Stainless Steel Polish (p# 21499) is not recommended on the black chrome tips — clean them with hot water and a microfiber cloth.
