2015-23 Challenger Hellcat MRT Extreme Cat Back : DMS

For the best performance and most aggressive sound from your third-gen Challenger Hellcat, upgrade your stock exhaust to the MRT Extreme Hellcat Cat Back Exhaust System. Our loudest, baddest sounding exhaust system we manufacture, the MRT Extreme Cat Back gives an extreme exhaust roar that will get you noticed on the road. Manufactured out of corrosion-resistant T304 Stainless Steel, the 3" mandrel-bent tubing increases exhaust flow, offering your HEMI engine the performance gains it deserves.

Extreme is the loudest MRT exhaust - even louder than Sport Touring and Street Race. It has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunity to Feel the Performance and is packaged in a design without the excessive drone. This system also includes the MRT-designed DMS (Drone Management System) to help reduce drone noise to an acceptable level.

A Performance Exhaust for Hellcat Vehicles
If you want an upgrade that gives you a lot of horsepower and sound per dollar, swap your factory exhaust for the MRT Extreme Cat Back Hellcat Challenger Exhaust. It's made in the U.S. and designed for DIY installation - it takes only 90 minutes to add to your vehicle using standard automotive tools. No tuning is required to start reaping the benefits of your new exhaust. All necessary components and hardware are included, and the system is inspected a minimum of four times for quality before shipping.
