Header tube band clamp????

I've got an offending section 1 5/8" header tube that I want to be able to remove and replace.

I've used stainless band type clamps in exhaust pipe butt connections with great results but I don't think they make ones that small.

Anybody know where I can get something like that for 1 5/8 pipe? Any other ideas for a removable section?
