i have a 04 crossfire and I have a magna flow full exhaust system in it. The problem is, where you would put the O-rings on to hold the muffler part up keep falling off and leaves the exhaust wiggling all over when i drive, its also hitting off something now and i can hear it when i drive. When I first got the exhaust put on i was told that O-rings are crap and would not hold up the exhaust so a metal piece was welded on to secure it, well that end up breaking off so i don't know how well the weld was actually done. I went back to the shop I got it out on at and they put two O-rings on, one on each side, those fell off the same day. I went back again so they put four O-rings on, two on each side, the left side rings are staying on but the right side rings keep falling off, I don't know what to do to keep them on. Anyone have any ideas? Is anyone else having or had this problem? I believe that for my exhaust to stay on for good and be secure, something just has to be welded on
