GMC Sierra 1500 Performance Exhaust - Rear - Borla - Cat Back S-Type - Black Chrome - `14-`18 is a direct-fit rear section Cat-Back system designed for 2014–2018 Sierra 1500 models. It delivers the distinctive Borla Sound of Power with durable materials and a black chrome tip finish.
This S-Type Cat-Back rear system uses Borla's patented straight-through and multi-core technology to improve exhaust flow and responsiveness without compromising drivability. Fabricated from premium T-304 stainless steel with ultra-smooth mandrel bends and precision CNC manufacturing, the system is built for long-term corrosion resistance and an accurate fit. The Black Chrome tips provide a stealthy appearance; do not use Borla Stainless Steel Polish p#21461 on these tips—clean them with hot water and a microfiber cloth. The design routes 2.75" inlet into dual 2.25" outlets with 4" split rear exits for the intended fit and sound on applicable Sierra 1500 configurations.
