Flowmaster's Force II® Cat-back exhaust system for all 2011-2021 Dodge Durango R/T, Citadel, Limited, Pursuit and Special Service models with the 5.7L Hemi engine, as well as the 3.6L engine, is perfect for the person looking for mild to moderate sound levels with all of the performance benefits that you would expect from Flowmaster®. This bolt-on emissions-legal system for the 5.7L Hemi engine features all mandrel-bent 2.50-inch stainless steel tubing with a pair of specially tuned resonators flowing into a Scavenger Series® X-pipe for maximum power and a unique deep muscular tone. The Scavenger Series X-pipe flows into a pair of specially designed 60 Series™ mufflers that have a healthy deep sound outside, but helps keep the interior resonance down to a minimum. The mandrel-bent 2.50-inch tailpipes exit in the factory locations and are finished off with a pair of large 4.00-inch polished 304S stainless steel logo tips. This exhaust system covered by our Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: Fits 2 & 4 Wheel Drive models.
