    Great-Sounding System. Balancing the scales between the need for a durable system and a good fit for your budget, the MBRP XP Series 3-inch Single Side Exit Cat-Back Exhaust for your 2014-2018 GMC Sierra is made from medium-grade T-409 stainless steel. While this steel often discolors, it won't rust or corrode, and the T-304 stainless used for the highly polished tip will never fade or dim. You may see up to +5-10% horsepower and torque gains as the system's high outflow drains off backpressure and lets the engine run freer and stronger, along with +1-2 mpg gas savings. The sound is the heart of the XP Series, though – changing the exhaust note to a deeper, fuller rumble that remains smooth and pleasing.

    Sturdy Build. The T-409 stainless steel construction renders this MBRP XP Series Cat-Back mostly immune to rust and corrosion, as recognized by MBRP's limited lifetime warranty. The 3" piping features 16-gauge walls for extra burliness, while the 4.5" exhaust tip is mirror polished aerospace quality T-304 stainless steel.

    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 designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's equipped with a 4.3L engine.

            Rumble

            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.

            2018 GMC Sierra

            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.

            Great sound ! Has a deep throaty sound, just what I was looking for ! I gave 4 stars because I had to cut about an 1-1/2” off for the hanger not to hit 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.

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

            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
