The MRT Street Race Axle-Back system will push your Challenger to the next level with an aggressive bite and deeper growl. Offering race-track level street performance to match, this handcrafted, corrosion-resistant T304 Stainless Steel system features T304 polished SS 4" tips and 2.5" mandrel-bent tube to increase exhaust flow (matte black option available). We engineered the best sound to match the Challenger vehicle and provides increased performance from the increased exhaust flow. Choose this system if you want the aggressive muscle car attitude to be present at all times but with minimal drone - open that throttle wide to release the sound and push the limit.
For Challenger customers with factory installed Active & Dual Mode Exhaust valves, MRT offers and recommends a simple solution that allows you to upgrade your exhaust system without having to develop a tune. For more information on these plates, refer to
