Which header (not brand) works best in an ek hatch with a gsr swap? As far as it lining up to the rest of the exhaust system.

 

I have a gsr swap in my ek coupe and im using the header from a b16. I think b- series headers (B16 and B18c) are the same. But if your buying from a dealer get the one that would go with an EM1. Correct me if im wrong peeps

 

if i remember correctly what i have read and heard, almost all b-series engine components are interchangeable, hence the ls/vtec. now if the header bolt pattern is the same im not sure.
