What's the major difference between the DC's F22B2 header and the F22B1? Also, what would it take to make it fit. Thanks for the help.

 

Just a guess, 02 sensor.

 

f22b1 is a 4-2-1 design...b2 is a 4-1 design

 

So it will work?

 

Anyone?

 

What will it take to fit what onto what? F22B1 header onto a F22B2 motor or visa-versa?

I sold my 95 EX (F22B1) header to someone with a F22B2.

What I think you'll need to is...
If you have a F22B2 and your buying a header for a F22B1 you'll need to relocate the O2 sensor to after the header, before the cat. You may need to buy the small piece of pipe (#7 in the diagram below) from the EX to mount the O2 sensor.

If you have a F22B1 and you're buying a header for a F22B2, then you'll need to relocate the O2 sensor into the front of the manifold and remove the small piece of pipe from the exhaust where the O2 sensor used to be.

The above was for stock manifolds but the as long as DC makes manifolds seperately for the vtec and non-vtec motors (sorry, haven't looked at headers in a while) then the same should apply.

 

Thanks, I could get a good deal on an ex header, but it seems that I should just spend the extra $ to get one specifically for my F22B2.
Thanks for all the help.
