    Enhance Your Truck. Amazing new looks and sound are at your fingertips with the MBRP Installer Series 3-inch Single Side Exit Cat-Back Exhaust, a quality yet frugal upgrade for your 2014-2018 GMC Sierra. Enhancing your truck's exhaust note with a rich baritone rumble that is free from cabin drone thanks to the muffler's absorptive design, the system dresses up your pickup with a 4.5", brilliantly polished exhaust tip, too. Cutting exhaust temperature by 200° F and enabling much faster outflow of the fumes, the Installer Series Cat-Back wins +5% to +10% horsepower and torque gains. Other benefits include +1-2 mpg fuel efficiency, longer-lasting oil, and superior throttle response.

    Designed for Use. The MBRP Installer Series Cat-Back is a high utility component, made out of aluminized steel that gives decent rust and corrosion resistance. The piping features 16-gauge walls, plus aluminum silica on the seams where rust is most likely to develop. The 4.5" tip is T-304 aerospace stainless steel and thus won't rust, corrode, or discolor with time.

    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. This MBRP Installer 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.

      Perfect

      This exhaust system was exactly what I was looking for in the sound and ease of instillation department. Fit up super quick and painless with zero issues and sounds amazing! Highly recommend to anyone and everyone.

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

      Perfect tone with very little if any drone!

      This is the exact sound I was looking for! Awesome for a daily driver just looking for a great sound. Super easy kit to install.

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

      Great pipes, easy install

      Just like stated its a simple bolt on kit, just undo one bolt and 3 hangers and it pops right on. Sounds great, loud on a cold start but quiets down when warmed up, no excessive drone at highway speeds.

      Very nice!

      "Some cutting may be required", indeed! I used an exhaust cutter to get the old one out, but once that was done, putting the MBRP in was piece of pie. Love the sound and apparent increase in power/efficiency.

      You need this

      This exhaust is mint. Took me a half hour to install. It has a solid rumble to it and it screams around 5 grand lol it pairs well with the Volant intake!
