I have B16a1 crx and I'm thinking about buying the dc header off of the 2000 si
coupe. I need to know if it will fit and do I have to do any mod to this header?
If I do, what do i need to do to make it work? Thanks!

 

the header will bolt up and clear the oilpan but you might need to have a muffler shop weld up an extension for the cat. convertor.

 

It will fit. But to make it work correctly with your engine, you need to run it with two O2 sensors. The header is designed for only one. The ECU with the first gen B16A was designed for two. Have a muffler shop weld in two sensor bungs in the correct locations.

 

It bolted up for a buddy of mine.
As long as you cat is in a stock location it should line up.

Exactly.

 

Thanks for the quick replies guys, so what you guys trying to say is that,
I need to have the muffler shop to relocate one of the o2 sensor and also
make another o2 sensor because it needs two? Then after that I have to cover up the orignal o2 sensor hole form the DC header? Man this is too much sh*t to do just for a header. Do any of you guys know where i can find a Header to fit without doing any mods. I know Hasport and Top End makes one, but it cost like
$400! So whats the best way to do this? Thanks again guys!

Either you do that, or get a JDM B16 header, or the Hasport one.

 

Koo! Thanks for the info.
