I am really dating myself here, but years ago there was a JDM build with all high quality stuff. The guy had a build log with a rear diffuser and the exhaust exited through the top almost like a blown rear diffuser. Does this ring a bell for anyone? I believe it was a cali S.

 

I'd start with google.
I simply googled S2000 Rear Diffuser JDM... then click on pictures and look through them. You may in fact find the car you're looking for. Then there will be a link to the picture location which will most likely be here on S2ki.
Hope this helps! Try other word searches too but you'll prob get most of the same pics.

Add "site:www.s2ki.com" (without the quotes, of course, to your google to only search this site (where the Search tool is pretty useless).

Was it a yellow AP1? Look up VaporS2k. Axle diffuser (front and rear), exhaust exit out of the license plate area.

 

nope. exhaust exited through the bottom of the diffuser by the axles i believe.

 

Diez? The diffuser and exhaust are made by AXLE.

 

^that's what I was thinking. This is also the perfect excuse for people to post more pictures of that gorgeous car.

 

YES! thanks guys.

 

Lots of pics here
