ATS turbo kit intake manifold hat question

Which intake manifold hat is used on the older ATS system? Is it the one where the inlet is angled up about 20 degrees like the one on the right? Or is it the one where the inlet is almost horizontal, like the one on the left?

Neither of your pics will enlarge in order to tell. Also, I could be wrong, but I think ATS had TWO older systems before the latest 093 system.

Thanks and I think you're right about there being two older systems. For the two hats in question, the one that that angles up is physically larger, and it appears that it would flow better. Also, the exterior of the casting is a little rougher. Someone else told me that is the one for the newer system. Does that sound right to you?

I bet you can go to Google and get schematics (pics) of all the parts to all the different ATS systems.
