hey guys i was wondering if u could help me out.... im looking to buy a header for my b18c1 in my eg hatch, i've heard that i need a B16 99-00 CIVIC SI header, is this true? also wondering if i got say and dc sports jdm 4-1 header for a b16, would the header clear my oil pan on my b18???

thanks in advance guys..

 

The B16 Header will rub on your oil pan, it will not fit a B18C properly. I would buy a header to fit a USDM Type R Integra and it should bolt right up. A GSR header will work but there is not a bung for your O2 Sensor, since the GSR cat has the hole for the O2 Sensor. The JDM ITR header will work but it has a larger collector, 2.5", and you would need to modify your test pipe or cat to accept the larger collector. Good Luck!

 

can't he just use the gsr cat with the gsr header? or does that cause exhaust fitment issues?

 

USDM type R or a 96 and up GSR header (has an O2 bung)
