Will a civic si (99-00) header fit a 2000 b20z in a ej8?

oh, and will the flange be compatible with my d16 exhaust? sry, I've searched around for info, but getting tired of sifting thru info I don't need and not getting an exact answer. There's a nice b16 header for 50 clams that I'd like to pick up on a local forum in the next couple of days.

It should mate with your exhaust. B series=B series, dont you love honda? If you wanna boost the power a bit, up the compression with a B16 head on that B20, great all motor starter, and will be able to make more use of that header (the higher the compression, the better responding to mods)

 

[mattliston]

I think Im wrong

Im seeing one side (left) that has no cat and the right side, which shows the bottom part of a header, a cat mounted. Whats your car's exhaust look like compared to this picture?

 

[mattliston]

Nope Im an idiot, 2 bolt straight no cat, or 2 bolt cat to 3 bolt piping. It will work!!

Then I come across postings like this:

Will a B16a header fit a B20? - Honda-Acura.net

Kind of confusing. Most aftermarket headers on ebay say they'll fit any bseries. hmm. anyone actually running the b16 header on a b20 / b18b?

 

[mattliston]

Sorry for any confusion I may have cause.

FACT Bseries headers fit all B series motors. this includes the B16, B17, B18, B20, and B21

FACT not all B series headers are same length....all will bolt on , this is true, but unfortunantly i cant remember, but i do know that while all B series wil bolt on they are not completely interchangeable because some of them do not clear or way overlear the oil pan

 

[mattliston]

Damn. I figured if it bolted up most likely it would fit the exhaust. My bad OP
