Can I put a header designed for the s14 on an s13 ???

I need to know if the s14 KA24de aftermarket header will bolt up just fine to the s13 KA24de. I know there won't be the bung for the AIV valve, but that doesnt matter since mine is removed anyways.

I don't believe so.

YES, it will bolt up just fine.

It's a direct swap...head mounting flange is the same, length is the same, flange at the cat is the same, O2 sensor threads are the same, etc...

EGR mounting is different IIRC, but that's a quick fix (or is easily removed).

And the S14 header will have a second O2 bung by the cat...so you'll need a plug for that...certain Honda oil drain plugs will work, IIRC it's a 18X1.5 thread plug that you need.

The "megan racing" header which is labled only for the S14 looks kinda funky. It seams there is only one pipe not two that connect to the stock down pipe (that's what I call it anyways). It's at Phase2's website under Ka24de. Would I also have to run a standard aftermarket downpipe for it all to work ??? Megan R has a downpipe thats made for the s13. Would those both connect to make a full lenght header down to the cat ??? Sorry for all the dumb questions, but I can't seem to find it anywhere (searched).
