It's just a U-shaped contraption with a bar across it that is tightened down by nuts on the ends of the "U", and available in the muffler/tailpipe section of any auto parts store. They're only good for light-to-moderate gauge pipe--believe me, I tried to crimp some heavy-duty stuff from the local muffler shop (my substitute for a cat converter) and I rounded the nuts off twice using a breaker bar before I could get the pipe to crimp (and it still wasn't tight enough). Pipe clamps can be a good thing if the crimp is sealed because they won't destroy the aluminized coating (if you're using aluminized steel) the way welding does. All-in-all, I would prefer welding because I hate the noise of exhaust leaks and my local muffler shop will weld a joint for me for about $5/joint.
