The Flowmaster American Thunder Cat-Back Exhaust System is engineered for 2005–2010 Dodge Magnum R/T, Charger R/T, and Chrysler 300C models equipped with the 5.7L Hemi engine. Designed for a perfect balance of aggressive exterior tone and moderate interior sound, this system enhances performance while delivering the iconic Flowmaster exhaust note.

Dual 2.50-inch mandrel-bent 16-gauge stainless steel tubing flows into Flowmaster’s exclusive Scavenger Series® X-pipe, providing maximum scavenging efficiency and a unique deep tone. The tubing then moves into a pair of Super 40® Series performance mufflers, featuring increased internal volume to handle the flow demands of the Hemi engine.

Finished with highly polished 4.00-inch 304 stainless steel tailpipes exiting straight out beneath the rear valance, this cat-back exhaust system uses factory hanger locations for a straightforward installation. All necessary hardware is included, and the system is backed by Flowmaster’s Lifetime Limited Warranty. Fits both two-wheel drive and all-wheel drive models.
