Exhaust Band Clamps

flingdingo said
The only band clamps I have used, join similar sized pipes together (e.g. 2 1/2 OD to 2 1/2 OD.)

I run these on my 65 Belvedere.From the headers to the mufflers to the tail pipes. As said above they should be replaced after one use.They have a stretch seal but I have reused them.
