: --------------=20 Wendell, Here is the place I got mine for around $100 for the 409 ss. The = 304 SS cost a bit more. You need to make certain you order the using = the right part number as that determines the inlet/outlet diameter. The = 12018400 is the - 2" T409 version = http://www.performance-curve.com/index.asp?PageAction=3DVIEWPROD&ProdID=3D= 621 There are many other sources, but this was the best price at the = time I ordered, search the web, you may find a better deal.

None I know of, Kelly. The 409 = alloy was=20 supposedly developed for exhaust type situation where corrosion = protection was=20 the aim rather than shiny polished 304, 316 or 321. Mine have = shown=20 no deterioration but they have few hours on them. Tracy = probably has=20 more hours with one that any one - but, I don't know which one he has = for=20 certain, although I think I recall him saying he purchased the cheaper = one=20 meaning the 409.
