Looking for an aggressive, deep exhaust tone in every driving condition - start up, idle, steady state and of course, wide-open-throttle to show off the power of your Hemi V8? Handcrafted for the Dodge Charger SRT8, as our loudest and baddest system, the MRT Street Race Axle Back will give you the exhaust roar worthy of your Hemi. Step on it for an exhaust growl with a bite that screams "take no prisoners." This exhaust is handcrafted in corrosion-resistant T304 Stainless Steel with dual polished 4" exhaust tips and 3" mandrel-bend steel tube. The increased diameter results in performance gains you will notice. For a more stealth like finish, a Black Ops black matte tip finish is also available. This system is engineered for the best sound to match the SRT8's capabilities and provides increased performance from the improved exhaust flow.

Street Race is the loudest MRT exhaust sound profile. It is louder than MRT Sport Touring Axle back. MRT also offers 2 catback systems for the 2012-14 Dodge Charger SRT8.

For Charger 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 MRT Part #92G155 or simply add to your shopping cart before checkout.
