MRT Engineering 2019+ Challenger Hellcat MRT Version 3 Cat-Back : DMS - 92G165
The MRT Challenger Hellcat: DMS Version 3 MRT Cat-Back system has a loud, deep muscle car sound and is handcrafted in corrosion-resistant T304 Stainless Steel. Base systems include T304 polished SS 3.5" tips and 2.5" mandrel-bent tube. Black Ops black matte tip finish is available for an additional fee. This system is engineered for the best sound to match the Challenger vehicle and provides increased performance from the increased exhaust flow. Version 3 is the loudest MRT exhaust. Louder than Version 2 & Version 1. It has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunity to Feel the Performance, and packaged in a design without the excessive drone. This system also includes the MRT designed DMS (Drone Management System.)
