Description
The Flowmaster Flow FX Cat-Back Exhaust System is engineered for the 2015–2016 Dodge Challenger R/T equipped with the 5.7L HEMI engine, delivering an aggressive exterior exhaust note with a controlled, moderate interior sound level. This system is ideal for drivers who want maximum performance and sound without excessive cabin drone.
Constructed from mandrel-bent 409 stainless steel, this cat-back system features dual 2.50-inch exhaust piping that flows into Flowmaster’s exclusive Scavenger Series X-Pipe crossover, improving exhaust scavenging and overall performance. The exhaust gases then exit through a pair of Flow FX straight-through absorption mufflers, designed to maximize horsepower while producing a deep, aggressive tone.
The mandrel-bent tailpipes are designed to use factory hanger locations and exit through the factory exhaust bezels, maintaining a clean, factory-style appearance. This system is dyno-tuned for maximum performance, includes all necessary hardware, and is designed for an easy at-home installation. Backed by Flowmaster’s Lifetime Limited Warranty, this exhaust system offers long-term performance and reliability.
