MRT Sport Touring Axle Back w/ DMS (92T122) - 2019+ Chevy Blazer RS 3.6L
Take your Blazer RS to the next level with the MRT Sport Touring Axle Back Exhaust, engineered to deliver a refined yet aggressive performance tone that complements the Rally Sport platform. This system provides a smooth, controlled sound during daily driving while delivering a bold, sporty exhaust note when you step on the throttle.
Constructed from corrosion-resistant T304 stainless steel, this system features 2.5 inch mandrel-bent tubing and a straight-through muffler design to improve exhaust flow and performance. MRT’s integrated Drone Management System (DMS) helps reduce interior resonance, keeping cabin noise to a minimum while maintaining a strong exhaust presence.
