Anyone else ever have this issue? The piece that goes over the axle has been rubbing on the chassis to the point where there is now a 1" hole in the chassis/frame. I have a magnapack catback and never got the passenger side to fit right. To make things worse, while I was away my bro in law put welds on the bolt on pieces. The drivers side is perfect, and I tried to replicate the same direction on the pass side but it will not fit the same. Turn one piece and it hits the gas tank, turn the other and it hits the frame, turn that piece that goes over the axle and that piece is now resting on the axle. Took it out for a quick spin and the catback rubbed an impression into the axle tube. I've been working on this damn thing all day and it will not fit. So I got it to not hit the frame and tightened all back up. Drive it. Come back home, lift it up, and the damn piece is back to hitting the frame. No idea how it moved. Really getting tired of mustangs.
