i am getting a 91 crx si and putting a b16 in it. i was wondering if there is a header that will bolt straight up to the stock exhaust without doing any work.

oh and i have searched and everything i looked at didnt answer what i was looking for

 

99-00 Civic Si header will fit. 2 o2 sensor bungs will have to be welded in the #1 and #2 pipes though if its a JDM b16.

The header will bolt up to stock exhaust fine. I used a Greddy SS 4-2-1 and fit great. Couple friends are using DC headers also.

 

thanks. i think the swap is a jdm one but no for sure havent looked at it yet. so the jdm one has 2 sensors??? and i know the one on hte bottom of the 99 00 civic one has one by the flange. do i need to plug it or is it where the acutal o2 sensor goes for the swapped b16 into the crx

 

The JDM OBD-0 B16a using a pr3 or pw0 ECU require two o2 sensors on the upper part of the header, the single o2 bung on the Si header will need to be plugged with a bolt (I used the old o2 sensor of my d15 engine to plug).

 

cool thanks

 

apparently hasport now has a header for a b16 crx that bolts up to the stock exhaust. it also has the o2 bungs pre installed up top.

i seen that the other day but i have access to a 2000 civic si header and have access to a welder so its next to nothing for me to do it instead of paying that much for one considering i go turbo asap with it then that header is a waist of 200 dollars

 

I just put on a us type r header on my friends first gen b16 and we didn't connect the second o2 senor and no cel was thrown weird but it runs better than before i dunno....

USDM ITR is an exhaust manifold, those sux0r.

DC sucks, I had a DC.. Cheap! One bottom out will crush a DC... Nothing will dent my ITR

 

so does a dc 4-1 header for a civic si have a bung hole that needs to be welded? and where do the new holes go exactly?

Dude my dc was destroyed, i had a gsr one (10mm higher than b16a) and my car was slammed so that header was crushed in half, plus the ss is real shitty because my started to oxidize badly

Yeah... had the SAME problems with my DC.

I've slammed my new ITR on accident, and no dent at all.. the header tubes are bigger, bigger collector too. Honda quality, can't beat it.. literally
