    Thrifty Exhaust Upgrade. If you prefer the look of two exhaust tips jutting out from under your 2014-2018 GMC Sierra’s tailgate, the MBRP Installer Series 3-inch Split Rear Exit Cat-Back Exhaust has this configuration, in a budget-friendly aluminized steel format. This Installer Series exhaust offers a mellow, rich exhaust note with just the right level of authority, while remaining quiet enough for an enjoyable drive. Exhaust fumes glide out through the open muffler and constant-diameter mandrel-bent tubing, so that they don’t pile up and stifle the engine – a setup that releases +5% to +10% more horsepower and torque, together with +1-2 mpg fuel efficiency gains.

    Sturdy Aluminized Construction. The MBRP Installer Cat-Back is built from 16-gauge aluminized steel 3” piping, which provides moderate rust protection and keeps costs lower. The tips are made from T-304 stainless steel, an airplane grade that will never rust or tarnish. The part comes with a 3 year limited warranty from the manufacturer.

    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 with 4.3L engines.

      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
