A high-performance 2012-14 Dodge Charger SRT8 exhaust system turns things up a few more notches while sounding like the Charger muscle cars of the 1960s and 1970s. Your ride will be the envy of fellow car enthusiasts and track day regulars yet remain street-legal for everyday driving. Order this aftermarket cat back exhaust for 2012-14 Dodge Charger SRT8 V8 cars with the confidence of a limited lifetime warranty.

Supersize Your Charger Performance

We use the finest materials to handcraft every MRT Charger exhaust system in the U.S. This cat-back is made of corrosion-resistant T304 stainless steel and is inspected a minimum of four times to ensure quality. Base systems include T304 polished stainless four-inch quad tips and three-inch mandrel-bent tubing for more efficient exhaust gas flow. A Black Ops black matte tip finish is available for an additional fee. This system is engineered to provide the best sound to match the Charger vehicle and provides increased performance and fuel efficiency from the wider tubing.

The Street Race Charger Exhaust is a performance exhaust that steps things up from the Sport Touring series. It has a constant exhaust presence with elevated sound to Get Noticed and plenty of opportunity to Feel the Performance while being packaged in a design without the excessive drone. With all that, our Street Race exhausts are street-legal in most states and municipalities, though you should confirm before ordering.
