ok i've searched about this already with no luck.
i've got a b16 in my crx, hasport mounts. and i currently have a dc 4-1 header in there. i've been looking to replace it with either a jdm itr header or a profab one. now i've searched to see which is better and of course found profab, which i had no doubt was the better one powerwise.

but i'm concerned of the fitment, all you ef guys know the crossmember clearance we were blesses with...

my question is could i bang on the crossmember a little to make one of theses header work? maybe a hack a little peice off?

and what about clearance issues on the profab with my radiator, i am aware that the oil pan clerance on the profab is sketchy but i have not problem fixing it.

please help and thanks in advance!

sorry about posting twice just looking for some help quick since i'm looking to order by friday!

 

i would'nt hack anything usually on the profab header it can fit on the b16 with maybe a little snug but measure the gap from the head mount to the radiator and see what the width of the header your purchasing is
