C-Back problem

[fireman02]

I installed Flowmaster's American Thunder c-back a couple of weekends ago and had a problem with the driver side tail pipe becoming loose and rattling against the frame where it goes over the axle. I tried adjusting and tightening the c-clamps that came with the kit, but after a couple of minutes of driving it would come loose again. So I ditched the c-clamps and bought band clamps. I thought the problem was solved but yesterday the same thing happened. I know the easy solution would be to get them welded and be done with it, but that makes it a pain in the ass to do work in that area like control arm upgrades and the like. So I was thinking of drilling some self tapping screws in with the clamps to hold the tail pipes in place. Has anyone here tried this?

I wouldn't use self tapping screws. That would just promote early rust holes in your tailpipes. Just use heavy duty muffer clamps. Maybe the ones before weren't tight enough.

if memory serves, the flowmaster cat-back systems use the clamp on the tailpipe to hang them-correct? my advice would be to take it to a muffler shop and get the hangers welded onto the mufflers a la stock style, and then the tailpipes will have less force dragging on them, therefore less chance of coming loose-then the band clamps would work better for you

I wedged pieces of wood in anywhere that looked close Before I tightened down the clamps, then after I pulled the wood out it caused extra clearance in the end.

I just put the same exhaust on my 93 gt and i had a little problem with the passenger tail pipe. I got my brother to help me and i lined it up made sure it wasnt hitting any thing and he tightened it. When you think you got it tight try to get it a little more and go back and fourth do each side a couple of turns thats what we did on mine and they havent come loose since that day.
