Some of the band clamps are stainless so they cost more. I would look for the band clamps that are "stepped" so one side goes on the outside pipe and is a little wider than the side that goes on the inside pipe. I actually cut the I-pipe on the cat-back and used a 3" butt connector. It seemed crazy to run dual 3" into the 2-3/4" knockdown at the front end of the I-pipe.
