Ken thank you for your advice, both in all your posts in various threads and the PM you sent me. We did not end up using muffler sealer on either joint. When you say "...gasket flush with the edge", you mean flush with the edge of the torq loopz right? There's maybe an 1/8" of gasket still visible outside of the loopz on the first joint, and we really hammered down the clamp right on the very edge of the loopz. Sound correct?
