07-18 GMC Sierra MRT Tough Truck Cat Back

Your Sierra deserves a sound that matches its attitude: aggressive, tough, and All-American. With the Sierra in mind, MRT designed an easy, All-American upgrade that will make you stand out and put you above other trucks. The MRT GMC Sierra MRT Tough Truck Cat-Back system is our loudest Sierra exhaust, letting out a get-noticed tone at idle and releases to a lively growl with an aggressive bite. This exhaust system is the louder of the two performance Sierra exhaust systems offered by MRT and sounds amazing -- you can actually hear the gear changes, there's a strong presence at steady state that's not obnoxious or offensive and you have to love hearing the burbles as you decel. Add a tough sound to match your tough ride.

We use 3" mandrel bent tubes and a 4" double wall to ensure your system increases your truck's exhaust flow and is built to last. We make all of our systems in America using corrosion resistant T304 Stainless Steel 3" mandrel bent exhaust tube and has a 4" double wall, increasing the quality of your exhaust system over stock. Along with a straight through resonator design, our systems reduce back pressure and increase exhaust flow, meaning more horse power you can feel. Our base system features a 4" polished stainless steel tip with beveled edges, but a "Black Ops" custom black ceramic finish is available for a small fee. If you are looking for a more subtle exhaust presence, check out our MRT Deep & Mellow line.

Application: 2007 thru 2018 GMC Sierra, 5.3 V8 engine
