      Superior Exhaust. A split side exit has several big pluses, including a deeper, richer exhaust sound and a fiercer, bolder look for your 2014-2018 Sierra and the MBRP XP Series 3-inch Split Side Exit Cat-Back Exhaust offers both along with premium quality materials and build. MBRP's exhaust system generates a rich, mellow exhaust note that is an improvement over stock without being earsplitting. Throttle response, horsepower (+5-10%), torque (+5-10%), and fuel mileage (+1-2 mpg) all gain from the installation, which pulls away exhaust fume backpressure so the engine runs more freely. The cooling effect even lessens the risk of breakdown and helps oil and lubricants last longer.

      Quality Manufacturing. MBRP makes the XP series out of T-409 stainless steel, a type that will last rust-free for a truck's lifetime (though it may discolor). The tubing is 16-gauge 3" pipe, with mandrel bends that minimize restrictions and turbulence in the exhaust flow. The 4.5" tips are made from gleaming, polished T-304 aircraft grade stainless steel that doesn't tarnish like T-409.

      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.

      The MBRP XP 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 that are powered by the 4.3L engine.
