This Flowmaster Force II® Cat-back exhaust system for the 2011-2014 Dodge Challenger SE models with the 3.6L engine is perfect for the person looking for a slight increase in sound over the factory system but with minimal interior sound and all of the performance benefits that you would expect from Flowmaster®. Features include dual 2.50 in. mandrel-bent stainless steel tubing flowing into a Scavenger Series® X-pipe cross-over for maximum performance with a unique deep tone. The exhaust then flows into a pair of our Delta Flow 50™ Series mufflers and exits into 2.50 in. mandrel-bent tailpipes that utilize the factory hangers locations for an easy installation. The tailpipes are fitted with specially tuned resonators keeping the interior resonance down to a minimum and exit out the factory exhaust bezels. Designed for easy installation, this system includes all necessary parts, hardware, and detailed instructions. Note: This kit only fits vehicles with integrated rear exhaust bezels.
