Contacted him and he no longer does them in 321, only 304 with 321 flanges. He did an initial batch of 10 in all 321, but the market just wasn't there to support it. That was back in 2003 or 4 and about the same time cheap headers started coming in from Thailand, and you could buy them for $600 on eBay.
He also said he sourced his 321 tubing from Burns.
thanks, i visited burns stainless steel, as you can see the price are not so competitive, you do think that my manifolds need about 3-4 - curves to do each pipe!
Between few time the two tests will be finished, one on my 575 and one on the 550 on track, i hope will be ok. Burns Stainless LLC - 321 SS Tubing ~ U-Bends
today i have found a titanium pipe OD 38mm Tkm 1 mm, the supplier told me that dimension is used for exhausts, unfortunately they not bend pipes ....
I asked to them a bid for pipes and plates (water cutted) for two set of manifolds, not for the cat.
My welder company weld Ti without problems, they welded Ti parst for Ducati.
If the price will be interesting, i will pass to the next problem, find a bending company ....
I think if exhausts will be be my future business,the solution to disengaged me from the suppliers is buy a bending machine!
Every time that i ask a particular thing, all answer me no!
