any B Series header will fit (with the exception of the B20A header I think)Quoted post[/post]]
I'm wanting to put an aftermarket header in the '91 si Crx/b16 project, and was just wondering what other companys make them for my body style(besides Hasport and there $400 one)?
Will the 90-93 integra headers fit???
Thanks

see how that one has the o2 sensor bung on the down pipe? the pr3 and pw0's o2 sensors read in cylinder pairs. one reads cylinders 1 and 4, the other reads cylinders 2 and 3. If you put both sensors on the down pipe, it won't read properly.Quoted post[/post]]
Thanks GSRCRXsi, you nailed it on the head.
(just to be sure)
I can use ANY b16/18 header if I have the [2] o2 'bungs' welded onto the header.
Like this one?

so you only need the two o2 sensors with a stock rex ecu? and how do you use the stock ecu? what about the VTEC?
plus if this is the case (reading cylinders 1,4 and 2,3) then you can only run 4-2-1 pipes. (the ones in the pic were 4-1) Im more curious about the stock rex ecu thing
