I need some help figuring out how to remove the OEM exhaust tips. I bought the trackhawk tips and from everything I've read it sounded like an easy mod but I've been stuck trying to get my OEM tips off. I've removed the bolt from the clamp, sprayed where they connect to the resonators down the penetrating oil, and smacked them every which way with a rubber mallet and they are not budging. Does anyone have any advice on how to remove stubborn OEM tips?
