    An Economical Solution. Providing the same rich sound profile and welcome power boost as MBRP systems made of more costly materials, the MBRP Installer Series 3-inch Split Rear Exit Cat-Back Exhaust is made for upgrading your 2014-2018 Sierra on a budget. Fabricated out of aluminized steel, the Installer resists rust for years and has a pair of rust-proof T-304 stainless steel tips that add a bright, bold touch to your pickup’s looks. The sound from this system is a mellow growl that’s more macho than stock without being overwhelming. +5-10% increases in horsepower and torque can result from installation under good conditions, plus a +1-2 mpg rise in gas economy.

    Constructed from Aluminized Steel. This MBRP Cat-Back is made from aluminized steel, strengthened by aluminum silica on the seams and welds to quash rust before it gets started. The Installer Series features 16-gauge 3-inch tubing, a chambered and welded muffler, and 4.5” stainless exhaust tips. This part has a 3 year limited warranty from MBRP.

    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 Installer Series 3-inch Split Rear Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's powered by a 5.3L engine.

      Review from MBRP 3 in. Installer Series Dual Exhaust System - Rear Exit (14-18 5.3L Silverado 1500)

      Awesome and affordable!

      I decided to get this after watching Adam's review. This exhaust is probably the best bang for your buck! The exhaust has a great deep and throaty sound for guys who are looking for just a little rumble without losing the class of your truck. My only issue with it is that when your truck goes into V4 mode around 70MPH, it starts to sound a little funky. However overall, the sound is great! Install wasn't that difficult for someone without too much mechanical knowledge. The most difficult part was getting the old exhaust out over the axles. I ended up cutting it out with a sawzall. Thanks American Trucks!

      Review from MBRP 3 in. Installer Series Dual Exhaust System - Rear Exit (14-18 5.3L Silverado 1500)

      MBRP dual exhaust

      Opened the package and everything was included to install the exhaust. All the pipe ends fit well together, just slid them in and clamped em down! The tips lined up pretty well when I was done, just had to wiggle here and there to make it look sweet! Truck sounds like a truck now!

      Review from MBRP 3 in. Installer Series Dual Exhaust System - Rear Exit (14-18 5.3L Silverado 1500)

      MBRP Exhaust Install

      The system came complete with all fasteners, clamps. The install went well, until I reached the driverside rear hanger bracket (supplied). when the system was completely installed , I noticed that the drivers tailpipe was hanging 3 inches lower than the passengers. I had to spacer the bolt on bracket up inside the frame rail to make the difference. Looks good, sounds awesome, overall happy. J Carter Texas
