My exhaust tips are not completely round at the base and will not fit onto the catback. It is more of an oval shape. Now after trying to get it on I can not get it off. Has anyone had these problems or any and how did they fix it. The tip is sticking out about 2 inches too far now and are hitting the hanger or the bumper. I am worried about the heat messing up the paint or the bumper. Help! Other than that I love the sound, looks, and fitment.
