      Enhance Your Truck. Amazing new looks and sound are at your fingertips with the MBRP Installer Series 3-inch Single Side Exit Cat-Back Exhaust, a quality yet frugal upgrade for your 2014-2018 GMC Sierra. Enhancing your truck's exhaust note with a rich baritone rumble that is free from cabin drone thanks to the muffler's absorptive design, the system dresses up your pickup with a 4.5", brilliantly polished exhaust tip, too. Cutting exhaust temperature by 200° F and enabling much faster outflow of the fumes, the Installer Series Cat-Back wins +5% to +10% horsepower and torque gains. Other benefits include +1-2 mpg fuel efficiency, longer-lasting oil, and superior throttle response.

      Designed for Use. The MBRP Installer Series Cat-Back is a high utility component, made out of aluminized steel that gives decent rust and corrosion resistance. The piping features 16-gauge walls, plus aluminum silica on the seams where rust is most likely to develop. The 4.5" tip is T-304 aerospace stainless steel and thus won't rust, corrode, or discolor with time.

      Easy Installation. The installation process of MBRP Cat-Back Exhaust is easy and the exhaust system can be installed with common hand tools. The bolt-on, no weld design provides you with a hassle-free installation process that can be completed in approximately 1-2 hours. Depending on your cab and box size, some cutting to the piping may be required.

      Application. This MBRP Installer Series 3-inch Single Side Exit Cat-Back Exhaust designed to fit with all of the cab and box configurations available for the 2014-2018 4.3L GMC Sierra 1500 models with an one-piece driveshaft.
