I am in the process of building a stainless log manifold, and I came across a log type turbo flange from BMCrace. Has anyone on here been using these, any problems. I was wondering which rod you guys would choose to weld stainless to HRS.

 

The BMC flanges are the only ones I use. They are great flanges. I use 309L on them with 304L runners.

 

Here is 304L to the HRS BMC flange on the last mani I made.

 

Yeah, from what I've read, 309L rod will do the trick.

 

309l is correct
