Like title says, swapping my b16 into my ek hatch tonight and want to know if stock b16 header (99-00 si) will bolt up to exhaust, have a apexi ws2 exhaust, I know from previous installs that this exhaust will bolt up to a gsr swap in ek hatch and eliminate the cat, but was told the stock 99 si header was longer....anyone know from experince? Any help would be appreciated

 

For future reference I tried it last night and the apexi ws2 exhaust bolted right up to the stock b16a header, and eliminated the cat. Also the stock exhasut did the the same thing, but the stock piping is way too small. Well I decided to follow up on what I found to maybe help the next guy.
