The Mustang GT Extreme 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 4-inch tips and 3-inch 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 your GT and provides increased performance from increased exhaust flow.

MRT has engineered a DMS (Drone Management System) for this Cat-back to give it the most pleasant ride experience. The MRT Extreme Cat Back is the loudest MRT cat-back. It is louder than the Sport Touring Exhaust.

This Badass series has just enough exhaust presence with elevated sound to get noticed! Feel the Performance note and packaged in a design without excessive drone.

IMPORTANT INFORMATION: For 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.
