I don't think I have seen anything bigger than a set of 1 7/8 headers. Anyone know of something bigger?

Kooks makes a 2 inch primary header for the F-body.

Not Unless its custom work.
Not many people have an application necessitating that much flow, So nobody takes time to develop a product. Except Kooks maybe.

I wonder what kind of build would support that well..

I'm interested in seeing what my 402 with L92 Heads would do with a 1 7/8 Header..

BTW, I have been running the 2" Kooks all year and we picked up a solid .1 and 1.5 mph going from the 1 7/8 to the 2" on nitrous and it did not loose any power on the motor(dyno tested)

George is the man!
Great product with no issues!

Thanks guys.. I'm running F-body Edelbrock 1 3/4 stepped to 1 7/8 in my 63 pick up. I've been kicking around the idea of a decently big cube motor with a lot of spray. Wanted to see what was available off the shelf.
