ATR header size?

[Darin]

Does anyone know the size of the tubing used on the ATR headers? Looks to be approx 1.5-1.75" on the primaries, and maybe 2.25" on the crossover?

I kinda want to build a basic set, mainly just to see how I do. Because I have sooo much free time with a 2 year old running around...

Also, anyone know where to get a set of header flanges for the V6? I guess I could chop down a set of SBC flanges?

I had a few sets of flanges water jet cut back in the day, still have a few sets around.

Think they are 1/2 inch thick, mild steel. PM me if your interested.

I don't remember the size, but I don remember always thinking that they were smaller than I expected.
