Exhaust clamps for lap joint 1.75?

Yea I am wondering the same thing in terms of room. My existing muffler is 16in long, the new muffler is 14in long. These reducer things, not sure how long they are but I do not think I would have room to then add all the Lap Bands. It is only complicated because I am trying to reuse the exisiting pipes. someday I will probably upsize the entire system, which probably means this new muffler would be ruined. But it was only $70 shipped.
