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

 

Is the problem that the ends of the new muffler bracket aren't curved down enough to contain the rubber hangers? Try using a long heavy duty(3/8'wide)HVAC zip tie. Run it through both the rubber hangers on each side, reach in w/ long needle nose and cinch it up to your desired stretch point, then cut the excess. As long as it isn't touching the muffler, it won't melt, promise. It is amazing how strong these ties are. It's not a pretty fix(but who sees down there), and may work for you. Your muffler shop sucks if they can't figure out a proper way to secure it. The bracket may need to be modified, welded,bent, curved?? But you definitely want rubber isolaters of some sort there.

 

Once the muffler is positioned where you want it, be sure the 3 bolts on the flange are tight. And on the Magnaflow, the extra connection clamp bolt needs to be really tight to keep the pipes from rotating.
