OK, I have a stainless exhaust pipe and muffler on the other bike. And it is blowing exhaust.

Last time I put a automobile clamp on it cause that SS is some tough & strong ... ah.... metal.

I got a gas leak, is there any good product that I can put in there to seal it better that will hold against heat?
I can't get it to tighten without popping my eyeballs!

 

If your talking about the slip on muffler joint try some high temp RTV. Available at any auto parts store.

 

Yea, at the join where one slides on. I looked VersaChem Hi Temp at Autozone, I didn't realize that that epoxy stuff could take 1000 degrees, I hope I can use it and still take it off later.

 

This is all you need. Will allow disassembly later on.
