      Throaty and Intense Growl. Upgrade to a powerful exhaust system with an optimal sound quality. This Thermal R&D Cat-Back Exhaust gives your Challenger a significantly perceptible confidence with its aggressive exhaust note and high-powered driving performance. In addition, the resonant tuning chambers innovatively produce moderate interior sound with an overall improved quality and control.

      Maximum Performance. This Thermal R&D Cat-Back Exhaust features a high-flow, straight-through muffler design with superior capabilities in scavenging the exhaust gases. Its 3-inch diameter tubing and dual chambers regulate precise shifts to maximize power gains. Furthermore, the mandrel-bent tube minimizes blockage and back-pressure, facilitating a sustained powerful exhaust flow. The resulting increase in horsepower and torque provide the Challenger with a significantly improved overall vehicle dynamics, both on the street and on the track.

      Supreme Durability. Thermal R&D designed this cat-back exhaust system for long-lasting durability. It is constructed from premium 304 stainless steel with mandrel-bent tubing, fortified with a polished finish. Moreover, its fully-welded structure increases mechanical protection from crimps and dents. This exhaust system is designed to handle harsh driving conditions, including the constant attacks from the corrosive exhaust gases and thermal stress from catalytic activities.

      Straightforward Installation. This Thermal R&D Cat-Back Exhaust bolts directly onto the factory exhaust hangers and mounting points. This direct installation process takes approximately 2 hours and requires moderate mechanical skills.

      Application. The Thermal R&D Cat-Back Exhaust System is designed to fit 2015-2020 Dodge Challenger 6.4L HEMI models.

        Thermal R D

        If you do the mid muffler delete off the actual thermal exhaust it’s actually really loud. Between 1500 and 2900 rpm it likes to pop and crackle. And still zero drone especially versus the stock exhaust. Needless to say I am very pleased.

        Just right!

        The Thermal cat back system is amazing, it really wakes you up on cold starts! This system has a low growl at idle and low rpms but open it up and man it really gives you that aggressive sound these cars should have come with! Not raspy and no drone, it’s really a great upgrade. Only took a few hours to drop the stock and get this one up and let me tell ya, not only does it sound great it looks great as well. I love the chrome Thermal logo inside the blacked out inner tips, I thought that was a great touch!
