Hi
I will getting my headers and sidepipes back from the coater today or tomorrow.
Was wondering what do I use for material for the big square header to sidepipe flange. This collector face is flat and has the four holes in it. Obviously we have to cut something out for it.
Its not the slip joint style some have.

Where I work we have access to sheets of high heat stuff made by Garlock. I was also told of using sheets of copper?

What are you guys doing for this one
