    Deeper and Bolder Exhaust Sound. Match your Challenger’s distinguished presence with a powerful exhaust sound upgrade by using this Thermal R&D Cat-Back Exhaust. This exhaust system generates a consistently bolder and deeper tone, thanks to its resonated mid pipe and drone-canceling chambers that eliminate the low, monotonous rumble.

    Improved Ground Dynamics. The straight-through muffler design and mandrel-bent tubing free up your engine’s power by allowing a faster and more efficient flow of the exhaust gases. The smooth path without the restrictive angles and bends facilitate more power generation. You can also experience improved fuel economy alongside the enhanced performance.

    High-Strength Exhaust System. Built to handle high thermal stress and damaging corrosive attacks, Thermal R&D used premium T304 stainless steel for this cat-back system. It exhibits high corrosion resistance and exceptional mechanical properties for long-term utility. It is protected by a polished finish for additional durability while adding a distinctive shine in your Challenger’s undercarriage. Moreover, the rectangular exhaust tips display the Thermal R&D logo for a custom look and quality-brand recognition.


    Installation. Thermal R&D designed this Cat-Back Exhaust for a bolt-on installation. It works well with your Challenger’s stock exhaust hangers and attaches to the factory mounting locations. The installation process takes about 2 hours and requires moderate mechanical skills.

    Application. This Thermal R&D Cat-Back Exhaust is intended for use on all 2011-2014 6.4L HEMI Dodge Challenger models.
