Aggressive sound


This Flowmaster® Outlaw Axle-back exhaust system is for 2015-2016 Dodge Challenger R/T with the 5.7L Hemi engine, and is perfect for the person looking for a very aggressive exhaust tone inside and outside the vehicle. This bolt-on emissions-legal system features two sets of mandrel-bent stainless steel inlet pipes, one set for automatic transmission cars which are 2.25-inch from the factory and we bump them up to 2.50-inch, and a full 2.50-inch set for manual transmission cars. The tubing flows into a pair of race-proven stainless steel Outlaw® Series mufflers with 3.00-inch outlets and finishes off with polished Quad style 3.50-inch polished 304 stainless steel tips. Like all Flowmaster systems, the benefits include improved throttle response, power and a deep powerful sound both inside and outside the vehicle. The system is covered by Flowmaster's Lifetime Limited Warranty and includes all necessary parts and hardware for easy installation you can do at home.
