did the 94 integra come with 4-2 and 2-1 headers? does the 94 year headers fit on a 98? need to know asap!

 

they didn't come with headers stock, but you can order a 4-2-1 or a 4-1 header for it. as far as will it fit a 1998, i'm not to sure but i know that if they are both the b18b or both the b18c, then it will work.

 

all b-series parts should be interchangable but the connector to the cat may be diffrent and you may have to goto a weld shop.

 

98-01 the 2 o2 sensors are in the catalytic converter, where are they in previous models?

 

i believe here in the US they came with 4-2-1 cast manifolds.

 

If you get any 94-01 LS/RS/GS/SE, 97-98/00-01 ITR or 00-01 GSR stock exhaust manifold (a.k.a. header), it will fit your 98 LS. Your car is obd2, so it has 2 o2 sensors, one on the cat, and one on the header at the collector. All of the manifolds I listed above have the same setup. You cannot get a stock manifold from a 94-99 GSR though, as it has no o2 sensor in the header and will not bolt up to your cat. So, for you purposes, as long as the 94 you are talking about is non-gsr, it will work.

fergy016 - only 96-99 gsrs have two o2 sensors in the cat, every other 96+ integra, incl the 00-01 gsr had 1 in the cat, 1 in the header, as described above.

 

Ok so if you have header(s), where does the 2nd one go on your four banger?

thank you for the knowledge, I have always wondered!

Technically, each individual pipe is a header pipe, thus the 4 of them together can correctly be called headers. Header is also correct, as it is a single unit after being welded together.

Sorry, couldn't resist, even though I add nothing meaningful to the thread.
