Does anyone know(couldn't find on the wiki) the inlet/outlets of the cats and outlet of the headers?

I wanted to start piecing together a Y-pipe and Test Pipe system, but I wanted to make sure I had the right pipe sizes.

I'm sure there's some logic to this, but it's eluding me at the moment

If you don't have the time to do it right,
when will you have time to do it over again?

most of your test pipes will be from 2.25" to 2.5" and your y-pipes are going to be 2.5" inlets with a 3" outlet... your stock midpipe is 2.5".. this will cause a little rasp but it's not terrible IMO... the Nismo y-pipe has a 2.75" outlet i believe and I think the Tanabe Y pipe is stock sized with a 2.5" outlet... good luck with your search and the wiki is always a good place to find some info as most y-pipes should list the inlets and outlets

That was a great 5 years with the Z. Moved on to better mpg and regular unleaded.

Ah cool thanks. Yeah I checked the wiki, but didn't see any stock numbers.
