Question 1 5/8" Headers?

As some of you know, I'm turbo'ing my 3.2 Carrera.

I was going to use OBX or GSF headers, but I'm now thinking I may spend a bit more and get some B&B 1 5/8" headers, to suit the Carrera heads better, since the OBX/GSF stuff has 1 1/2" primaries.

Would those slightly larger primaries be of any benefit in turbo application? Better flow/spool, or would it be negligible?

How much do the 1 5/8" B&B's typically go for?
