I think the "lube" WavJamR is referring to is a paste that hardens with heat. I think it's called exhaust joint sealant.

That exhaust wrap is meant to be applied to the outside, I think.  If you put it between the muffler and exhaust, it might  make it difficult to remove the muffler later. If you put it on the outside, you should be able to cut it off.

I used a Dyna muffler.  It looks the same as a Sportster muffler, but has a different mount which made it possible to bolt it to the stock mount with two bolts. That meant it was mounted further to the rear, so I had to get a short adapter made to slip over the exhaust pipe and into the muffler.  This does not have any bend. I have not noticed any soot on the brake arm.  I think this is because the muffler is so far back.

OK.  If I use the Permatex stuff you're saying to give it 24 hours to cure.  Is that 24 hours and THEN attach the muffler, or 24 hours after the muffler is attached?

Also, is this applied around the header pipe and then the muffler placed over it?  Or is it applied to the joint after the muffler is mounted to seal it off?

Thanks!  Hopefully this stuff will cure in colder temps.  My garage isn't heated and I think its going to be around 40 tomorrow.   I wonder if this stuff is the type that it will cure "faster" by starting the bike and allowing the pipes to heat up?

Yeah, I'd give it the full 24 hours before running it to lessen the chances of blowing right out.  I didn't have much luck with that and finally wound up using the Suzuki gasket which has some metal fibers meshed in it.  I think I just used the stuff that was supposed to be used for exhaust and didn't try the red or gray high temp RTV though.  The exhaust sealant putty just kind of burnt up and blew out after about a week.  I hope it works for you.  Let us know!
