Anybody know where I can get a couple of feet of 6"OD stainless.
Doesn't
have to be in one piece.
Jerry, do you have any left over from when you made Mark's  muffler?

Some over-the-road semis use large diameter stainless for their
exhaust systems. Might want to check w/ some of the truck repair  shops
in Commerce City.

I rolled mine out of .063 321 and then tig welded the seam.  If  you
use 321 be sure to use 347 ss filler rod.   Jerry

Thanks Andy & Jerry. Both good ideas.

Why SS 321?  and not Inconel?  Of course price is one point.  Does 321
shrink little compare to 304?

Hi Doug,  good questions.  At the time I was told that the only SS  that would stand up to rotary heat was 321 provided it was  sufficiently thick walled, thus .063.   Inconel would be the  ultimate. I have never worked with it.  If the 321 system worked  well, it could be redone in Inconel if it eventually failed.     Jerry
