Flowmaster 17405 Details
The Force II® cat-back exhaust system for the 2005-2010 Dodge Magnum RT, Dodge Charger RT and Chrysler 300C with the 5.7L Hemi engine is perfect for the person looking for all the benefits of a performance exhaust system with a deep moderate exterior exhaust note, but without the interior resonance that most systems have. The system features all mandrel-bent 2.50-inch aluminized steel tubing and our exclusive Scavenger Series® X-pipe flowing into a pair of powerful sounding Super 40 Series™ performance mufflers for a moderate tone. The tailpipes have a pair of specially tuned resonators at the back for minimal drone inside the car and are then finished off with large 4.00-inch polished stainless steel tips exiting in the OE cutouts in the lower valance. Includes all necessary parts, hardware and easy to follow instructions and is covered by our 3-year Limited Warranty. Notes: Also fits all-wheel Drive models.
