Flowmaster Outlaw on Challenger is a beast!
Stock Challengers are way too quiet for a muscle car, so I deleted the resonators. The sound without the resonators was a big improvement, but after awhile I wanted more. The Flowmaster Outlaw Catback system was just what I wanted. There's a nice rumble at start up and idle, but when you stomp on the gas it just roars. Installation was straight forward and took about 3 hours for removal and installation. My Dewalt XR impact gun made installation a breeze.

On the plus side, this system was easy to install. It sounds great on start up and at idle. On the down side there is a lot of drone in the 2k rpm range, so pretty much all the time during driving. Also for the price I figured the whole system would be made of stainless steal. It isn%X92t, only the muffler and tailpipe are stainless. That%X92s a big disappointment. Overall take; spend a little more and get the Borla instead.
I was looking for something to make my car pop a little more. I%X92m completely gutted and all components have been changed. I went from a 3.5 to 2.5 exiting hole diameter. It pops but not as much as I was hoping for. But overall sound quality is nice. Doesn%X92t sound ricey. Good for what it is.
