what length header?
as the title says iam about to start my B20/vtec swap in my 98 civic sedan , and iam running a oem cat and oem exhaust and plan on running a oem header , which oem header do i need that will bolt directly to the factory cat with no mods needed to anything just a complete bolt on . iam trying to avoid shortening or lengthing anything if possiable ,iam guessing a B16 header like the 99-00 SI's but iam not sure if the height of a B20/vtec is different and if that would change anything TIA
b16 header fit my b18c5 just BARELY so if the b20 is much taller id say it wont
a b18C vtec header will clear your motor. but i dont think theres any combo of exhaust and cat you can use that will not require welding/lengthening of your cat to bolt up 100%
