    Power and Thrift. Offering the excellent sound and good performance boosts of the whole MBRP exhaust series in a low-cost aluminized steel format, the MBRP Installer Series 3-inch Split Side Exit Cat-Back Exhaust is your go-to option for an affordable upgrade to your 2014-2018 Sierra. Creating a full-toned but smooth and enjoyable growl, this exhaust makes you feel powerful without annoying your neighbors. The high flow that produces that sound also amps up performance, winning a bonus +5-10% torque and horsepower by easing backpressure for better engine aspiration. This also improves fuel use by +1-2 mpg and gives you better throttle response – as well as cutting the hazard of a breakdown.

    Cost-Effective Build. The aluminized steel used for the tubing in the MBRP Installer Cat-Back is 16 gauge, giving the 3-inch piping an extra measure of endurance. Aluminum silica defends the welds and seams, the spots most likely for rust to start. The 4.5" tips are T-304 stainless steel, which takes a flashing, glossy polish and doesn't darken or stain over time. Using the provided clamps and hardware, you can bolt this exhaust onto your truck in under 2 hours. The system comes with a 3 year limited warranty.

    Application. The MBRP Installer Series 3-inch Split Side Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's equipped with a 5.3L engine.
