    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 GMC Sierra's that have the 5.3L engine.

      Awesome System!

      This is a great kit, very easy to install. Perfect low tone for a truck and glad I went with the all stainless steel.

      Review from MBRP 3 in. XP Series Single Exhaust System - Side Exit (14-18 5.3L Silverado 1500)

      not impressed

      i have a crew cab short box and the exhaust did not fit the truck like the directions stated the pipe that went over the axle was to long causing an issues with the exhaust hangers towards the back. now the directions says if you have a CREW CAB SHORT BOX YOU DO NOT HAVE TO CUT THE EXHAUST PIPE. In my cause i did because the one pipe was different. So an hour job to me about 4 hours to finish. i would have returned the exhaust however the directions only give actual measurement for the pipe that runs from the converter to the muffler because you do have to cut it if you have a different cab and box configuration. So not knowing one pipe was not right i cut out my factory exhaust. So at that point i had to make it work. Not knowing the measurements of all the pipes i had to measure and cut a couple times but i got it to fit correctly. i like the sound but wish i would have gone with a different brand do to fitment issues
