What header for Ls Vtec?

[intenseneal]

I have a 4-2-1 ceramic no name header (DC copy) on my b18b right now. I have a tune and the header makes good power for my Ls setup. I am doing a mildly worked B16 head and plan to rev to 8k. Will the header I have now perform well or should I get a 4-1?

either the hytech replica tri Y style or the rmf replica narrow style 4-1. both of these make good power with lots of dyno charts out there to back up the claims. a random DC knockoff is better than stock, but there are better ones out there.

Yeah I have been looking at the hytech replica for a while now.

I ordered a BBP 4-1 header for a GSR. This was I dont need to replace my cat with a 2.5 inch.
