Hey i have a 2000 civic wit a Apexi n1 cat back on it, i am trading the axle back for a 00 civic si stock axle back. Will it fit directly or will i have to weld it in. I know the n1 piping is like 2.36 or something around there but not sure what stock si is

 

I *think* it will work just fine!

Why?

I had a Tenzo R axle back on my HX that I wanted to use after doing a full Si swap - instead of the stock axle back.

The Si exhaust plumbing was larger than the HX, however...

All I had to do was elongate the two holes of the mounting flange, so the spring-loaded screws that hold it together didn't bind against the side(s) of the holes!

You'll probably have the same situation - in reverse...

I suspect all you'll have to do is play around with the holes on the flange...

 

he has full stock si and i have full apexi n1, we are just trading axle backs, would it work out ok with out doing anything. I think it should.

 

Bump Does anyone know, this should be a pretty easy question...

 

it will be a direct bolt on for alll 92-00 civics......all integra 94-2001 will bolt onto civic n civics will bolt onto integras....easy n simple man... u should be cool garanteed

 

Im pretty sure your right with my questiion, but integra and civic exhaust you cant sway out... just so you know
