1 7/8 or 1 3/4 headers?

I'd normally say go for the 1 7/8 but I'd wait till I'd hear from someone using them along with a 727 (that way you know it'll work with the 200r4).

Cant wait. They have to be here and ready to install when I do this thing. They are supposed to work well with 727, but I think I'll call TTi on Monday just to be sure they will work with the 200R4.
