      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..

        Great Exhaust for the Money

        Install took around 45 min. The only thing that took a little time was getting the oem system out of the way because I didnt use a lift or jacks. Easy install. Great tone. Overall very pleased with the system.

        Excellent cat back for Silverado's!

        "For reference, my truck is actually a 2019 Silverado LD (old body style) 5.3 4x4 LT which is not listed in the vehicle selection dropdown" My assessment of the MBRP exhaust which I just had installed this morning: I took the truck out for a drive and did some city and highway driving. On startup it sounds great, acceleration sounds loud up until you get to cruising speed. I drove it at 70 and you can just slightly hear the exhaust at that point, No drone! (I have an AFM disabler installed) I wanted something louder but not to loud and this exhaust does just that. To compare I heard the Carven and it had to much like a high pitch sports car sound. I liked the Borla also but the Atak was too loud and the S-type didn't sound much louder than the touring. The MBRP XP seemed like the perfect compromise. It's loud enough only when you need it and it's has a nice deep sound which properly matches the truck. It sounds to me alot like something between a Flowmaster and Magnaflow. When I drive it now feels like the engine has been liberated. You can feel that it's less restricted! I took my wife with me and she was happy with the results as well. She was concerned for when we take road trips. As for quality, it seems very well made and came in a box where everything was packaged tight and intact. All in all I'm very happy with it and feel that it was money well spent.

        Awesome exhaust

        This is a great exhaust it's not to loud and has a nice deep sound. And it took me less than an hour to remove old exhaust and install the new one.

        Good quality product especially for the price compared to other brands. Very easy to install. It does have some droning in the cab especially when it goes into V4 mode.

        Great sound , just what I was looking for. I did have to cut about an 1-1/2" off one of the pipes because the hanger was against the shock.

        Does not fit

        I have a 2017 Chevy Silverado 5.3 crew cab, the exhaust does not fit, their is a bracket that holds the drive shaft in place and that’s in the way,now I half to take my truck to the muffler shop to get welded back to stock, and when I got the package it was beat up and the pipes where bent! Never buying from them again!

        Perfect sound and simple install

        I wanted a system for performance without being obnoxiously loud. You can tell it is there but there is zero drone inside the cab. When at cruising/highway speeds, you cant even tell it is there. This system claimed to NOT require cutting for my truck when in fact, I had to cut a bit off of the mid pipe for the installation. No big deal. Besides that, it was as simple as it gets! Super easy install, excellent sound and not overly-loud. Do yourself a favor and spend the extra money on the stainless system. I am so glad I did. The stainless system includes much higher quality clamps. I highly recommend this system for someone looking to upgrade without breaking the bank.
