Why does Borla make their exhaust hangers so long? The hanger by the resonator is rubbing on the underbody of my car. When around 2k rpm decelerating i get an awful rattle from it right under by center console area. Wedged a piece of rubber under it and stopped for a day. I could try to put a piece of vaccume tubing on the hanger. Any other suggestions and has anyone else had this problem?
