My car has a MAC catback on it from the previous owner and Im having some issues with it. First off, it doesnt rattle or bang around so thats good. However, the passenger side pipe that goes over the axle is rubbing the control arm and the brake lines. The control arm I can deal with but I do not want it touching those brake lines at all, I have heard stories about them rubbing through and that would suck. I have loosened the bolts and tried to adjust it, but it will hardly move. If anyone has had this problem and knows how I can go about adjusting it I would appreciate it.
