Slant Six Exhaust Mannyfold

I think you are splitting but hairs on this one Rusty. :)
Thank you. Drive through.

I've thought about that, but here's my thinking......however flawed. lol If I find a manifold with the larger outlet, say 2 3/16" then in all likelihood, it will have more meat in the throat to enlarge further. All of the 2" outlet ones I have here will either be very thin in the throat, or hit air if I try to enlarge them.

You may be right, but since I have no time limit, I can try. Thank you drive through. lol
