I've seen a lot of threads where turbo guys make their own exhaust manifolds... where do you guys get the header flanges to create your header? I just checked summit racing and they're in the high hundreds... is this average?

 

Vibrant Performance makes some.

 

I have been using collector rings to attach my exaust pipes, headers, extra. They make 3 bolt rings and 4 bolt rings and they are pretty cheap....

I got my SS ones from ebay, They were a $100 shipped i think for the pair. There is some steel ones on there some times for $80 I think.

 

Vibrants PN# is 1460L.
