2015-23 Charger RT MRT Street Race Cat Back

Your third-generation Dodge Charger RT can now sport an MRT Street Race Cat Back system that has a loud, deep muscle car sound like the original pony car. This system was designed for increased exhaust gas flow, less back pressure and better efficiency. Our automotive sound experts engineered it for the best growling sound to match the Charger R/T character, filling your driving experience with excitement and action. When you smash the gas pedal getting on the highway or coming out of a chicane, you'll get a remarkably aggressive bellow that's 100% street-legal.

An Exhaust Worthy of a HEMI

The original Dodge Charger was powered by the original HEMI V8 engine, and with the HEMI at the heart of the Charger R/T, we decided it needed a Dodge Charger cat back exhaust that could unlock its full potential. The exhaust is handcrafted in corrosion-resistant T304 stainless steel with 2.5-inch tubing that's mandrel-bent for optimal flow. By replacing everything behind the catalytic converter, you'll max out gains when you're at the wheel. We even use straight-through Dodge Charger mufflers to remove every possible restriction.

The MRT Street Race Cat-Back is louder and will have more rasp or drone versus the Sport Touring Cat-Back system (MRT Part # 92G146), though it can certainly be tolerated in the name of the monster sound. We sometimes refer to MRT Street Race exhausts as the Badass Exhaust series and it couldn't be more appropriate here because this exhaust sound typifies the R/T performance series with an aggressive muscle car 1960s sound saying, "Look at me - I take no prisoners (and welcome my friends)!." Rev up the RPMs with a badass exhaust that everyone will notice, is packed with plenty of opportunities to Feel the Performance and packaged in a design without excessive drone!

Bee the Star Any Road or Track

Since 2003, MRT has been designing high-performance exhaust systems for DIYers. This cat back exhaust for the Charger RT can be installed in 90 minutes or less using standard automotive hand tools and the included hardware. Drive off with the confidence of a limited lifetime warranty against material and workmanship defects.

For Charger customers with factory-installed Active & Dual Mode Exhaust valves, your vehicle will need a defeat device so your exhaust is 100% on for an exhaust sound that is full-time cool! MRT offers and recommends a simple solution that allows you to install an aftermarket exhaust to defeat active exhaust without throwing a check engine light code or having to develop a tune.
