Maxpower cat-back exhaust for Hellcats, latest electronic version. Used for less than 6 months. I bought it for over 5000, and God is my witness, but it needs the air device, which costs between 200 and 400 at most. And for those asking if it fits RT and SRT, yes it fits. And it fits Chrysler and Dodge. As for the Challenger, it needs a slight modification to the kit, but it fits. The price is 3400 final. The kit is brand new, brand new, and fully functional. Price reduced to 3400.
