Description
This Borla S-Type Cat-Back system transforms exhaust flow on 2014–2018 Silverado/Sierra 1500 trucks by routing a 3.5″ primary into dual 2.25″ outlets to deliver the classic S-Type sound with minimal in-cabin drone. Built from T-304 stainless steel with ultra-smooth mandrel bends and precision CNC manufacturing, the system increases exhaust velocity for improved throttle response, efficiency, and the distinctive Borla sound of power. Each tailpipe is finished with single 4″ round bright chrome T-304 tips, with a black chrome tip option available for a darker appearance.
