Does anybody know exactly what type of stainless S50 manifolds are actually made from??

Cheers, Ben

Just looking on ca automtive and ruff products stainless manifolds are listed on there, and it shows them using SUS 304 / T304 or whatever its called. Turner motorsport list themselves using T304 for the new E9X 3 series for the likes of the 335i.

I know that most use 304 or 308 for their SS manifolds but what are the originals made of??
I can weld them with MS wire but then the welds will rust and it makes a difference as to which wire you use on which base metal. You can use a 'higher' grade of wire but not a lower i.e. 308 wire on 304 or 308 metal but not on 316.
