Wuts up everyone.

Alright i just bought a DC JDM 4-1 Header and Im having some fitment issues. i have a stock 94 b18c1 in my 94 cx hatch. originally i had a 93 gsr exhaust manifold, 2000 usdm itr cat and mid pipe, and stock a stock cx muffler. first thing i noticed is that the flanges on the dc header dont bolt up to the itr catalytic conv. they are at totally different positions. another thing is the o2 bung. my o2 sensor doesnt seem to fit right on the dc header, so do i need to get an itr o2? i would have thought that they were the same. ive seen pics of other dc jdm headers and noticed that the collector flanges are different. anyways i check the box of the headers and it is noted as a 96-97 model. but shouldnt all jdm itrs have the same flange positions? do jdm itr headers even bolt up to usdm itr headers? can someone help me figure this out? thx

 

take off and twist the cat....to the other bolt pattern...

 

the jdm header has a bigger collector (2.5 inches) thats why dc came out with the jdm header because people wanted to run a bigger exhaust. why do people buy stuff because it said jdm and dont even know the difference. I have a jdm intake manifold for that b18c1 for sell.

 

no need to bag on me, just didnt know if jdm header would bolt up to usdm header. sorry for not having your almighty knowledge...

 

oh and check your grammar and you might actually get a buyer for that manifold
