I did not paint the parts and an exhaust shop did customize new hangers. The tips are easy to install once the stock resonators are in the correct position. Initially, the tips would not fit because the resonators were too far to the outside...tips hit the diffuser.
I thought it would be a simple bolt-on after swapping the diffuser, similar to the Challengers. Not quite, new hangers were needed to help slightly relocate the resonators.
