Guys,

Just out of curiosity, does anyone know what type of stailess tubing is used in high performance manifolds for the risers, such as stainless marine, or gills ?

And is it the same tubing inside an out (just a different diameter) ?

I thought it was 316L, but I wasn't sure.

Just one of those things I was wondering.

Thanks,
RJ

Rj,
You can order it at CP performance or I'm sure Ponz has some catalogs from tubing sources.

The CMI headers I just bought are 317L.
