      Excellent Performance. With this CGS Cat-Back Exhaust System, your GMC Sierra will have enhanced performance. This system provides your vehicle with long-lasting durability to outlast other cat-back systems in the marketplace.

      Durable Construction. CGS uses high-quality stainless steel that is 100% welded to manufacture this high flow muffler. The seamless tubing has a mandrel-bent, which ensures that the pipe airway is not restricted. Hot exhaust gases can then flow with less instability to reduce backpressure and preserve velocity of exhaust gas. The tip also is made from polished stainless steel.

      Lifetime Warranty. You’ll benefit from a lifetime warranty on this cat-back system. Emissions standards and the factory warranty are not affected by the CGS warranty. This system is street legal in all 50 states.

      Application. The CGS Motorsports Stainless Cat-Back Exhaust with a Single Side Exit is designed to fit the 2014 to 2018 4.3L GMC Sierra's equipped with the following cab and box configurations.
      • Double Cab with a Standard Box
