Right now on SummitRacing.com, the Flowmaster Flow FX cat-back exhaust system (part no. 717479) is available for $758.97 with free shipping. It’s comprised of 409 stainless-steel, and is described as having a “moderate to aggressive” sound. As with all Flowmaster products, the cat-back comes with a limited lifetime warranty on workmanship and materials, which includes rust corrosion.
As far as the quality of sound goes, we’d say this is a sufficient exhaust for those who want a happy middle-ground. With this exhaust, the Dodge Challenger will let out an authoritative growl under heavy load, but remain relatively docile around town. A good sign of any quality exhaust.
Have a listen for yourself, then let us know if you think the Flowmaster Flow FX cat-back exhaust system is a good fit for a Dodge Challenger R/T.
