About this product

Part #: B508-C513

Thermals True Helmholtz Technology for Optimal Sound For the 2015+ Dodge Challenger SRT and Hellcat models, the design engineers at Thermal R&D went to work on optimizing the sound to achieve a more aggressive tone that the engine deserves - all without letting in the drone. The final result: OEM style valves that work with the factory Active Exhaust System, a 3” diameter system, and sound control utilizing our top of the line engineering process. Dual drone cancelling chambers and a resonated mid pipe with balance mixing chambers allow for drone cancelling when cruising, but keep the aggressive deep, throaty notes on acceleration. Finishing it off, we added upgraded polished tips that are slightly bigger than stock, and polished with removable polished stainless logo badges. Thermal R&D Exhaust systems are designed with quality of sound and manufacturing as our number one goal. Built from T304 Stainless Steel, the fit and finish of our products are designed for performance on both the street and the track. Understanding that the exhaust is the starting point for many builds, our high-performance exhaust will allow additional modifications to perform at their peak. We engineer our products with the goal of achieving the best all-around product for a given application.
