I'm not sure, but a lot of people will take the exhaust from an R/T. You have the places for the hangers, you just have to have them mounted to the exhaust. Good luck with your choice of exhaust. This is the fun part of owning a Challenger, all the cool things you can do to them.
I appreciate the info. I'm trying to find an exhaust to where I can get some of that aggressive rumble.
