Description
Power Up Your Sierra. Featuring a rich, mellow baritone exhaust note that will bring a smile to your face and a refreshing new self-assurance your 2014-2018 GMC Sierra, the MBRP XP Series 3-inch Single Side Exit Cat-Back Exhaust is built from long-lasting T-409 stainless steel. The 4.5″ exhaust tip, on the other hand, is T-304 stainless, a higher grade that stays bright and clean-looking permanently. Exhaust sluices out fast and easily through the constant diameter piping and high-flow chambered muffler, not only generating the XP’s satisfying sound but also letting the engine spin up another +5-10% torque and horsepower. The exhaust also wins +1-2 extra miles per gallon.
Premium Endurance. The MBRP XP Series Cat-Back is for those who care more about rugged results than a perfect appearance. The T-409 stainless is permanent and lasts the life of your truck (limited lifetime warranty), and is more affordable, but will discolor a bit over time. The 3″ tubing has 16-gauge walls and is all-welded. The T-304 stainless tip, on the other hand, will stay fresh and bright permanently.
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. The MBRP XP Series 3-inch Single Side Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 5.3L GMC Sierra 1500 models with an one-piece driveshaft..
