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?
