Didn't do it today, but last week before I went camping I got new band clamps for my Flowmaster FlowFx muffler. I put it on 2 years ago and the pipes had moved slightly and when I tried to loosen the bolt they broke. I got Evil Energy band clamps and really like them. They cinch up real tight and exhaust hasn't moved since I put them on. The other clamps would occasionally allow the muffler to slide back slightly or pipes to move a little. I repositioned them multiple times. Grabbed the new clamps on Amazon.
