The MRT GMC Sierra MRT ToughTruck Cat-Back system is our loudest Sierra exhaust and is handcrafted in corrosion resistant T304 Stainless Steel. This system includes 3" mandrel bent tube and a 4" double wall, polished T304 stainless steel tip with beveled edges. It is engineered for the best sound to match the GMC Sierra and provides increased performance from increased exhaust flow. This exhaust system is the louder of the two performance Sierra exhaust systems offered by MRT.
Application: 2007 thru 2018 GMC Sierra, 5.3 V8 engine
Hear the Difference - How does it sound? The MRT ToughTruck Cat-Back #92T105G has a loud, deep muscle car sound.
- Is there drone or resonance? The drone is noticeable but tolerable.
- What if I step on it? Wide-open throttle increases exhaust loudness and tone to an aggressive performance sound.
