Unless I'm missing something, it is. So the design goal is to feed the exhaust gasses into the low pressure/drag area directly behind the license plate area, and thus increase wing and diffuser efficiency?

LOL! I read that while I was looking at the first picture, and I was confused at how a bucket of sand was going to improve the finished straightness/eliminate the inherent warping when added to the fiberglass resin....
And then I got to the sand picture and thought: "Whoa, when he said 'a ton of sand', I never considered the possibility that he used 'a ton of sand'.

Question for you guys who have installed a flat floor: I'm planning to go the "angle iron bolted to the pinch welds" route and also bolt in or support the panel to the frame. What I'm wondering is how the exhaust is going to route down around the diff to get to the back without getting in the way of the flat floor/diffuser.
Here is my current exhaust and you can see that there is no way to make it empty behind the bumper without bending lower.

I'm hoping ThePass or some of the other diffuser-wielding miata people can chime in on their solutions (maybe with pics? )
Thanks!

What would changing axles do?
And are you saying to route the exhaust to one side of the diff and up close to the axles?? I hadn't thought about routing above the axles but it seems like that would put a lot of sharpish bends in the exhaust. Below the axles and above the sub-frame brace seems like it wouldn't fit with the axles at full droop

Below the axles but above the bracing, with the 96+ you get a lot more room. I built my exhaust kind of sloppily with the 94 style axles and its scraped below the axles. If I was going to make it again now with the 96+ axles I could raise it up high enough to fit all 3 inches up higher than the cross brace.

1. To try to move the wake from the rear wheels outwards where it will cause less disturbance.
So the exhaust needs to add air to the back of car, not under it
2. To re-energize the low pressure air at the back of the diffuser to create more rear downforce.
re-energize the air in the diffuser that is slowing down due to an increase in volume.
I am thinking about using an elise diffuser with the exhaust outlet in the middle of the diffuser for just these purposes. Under the car before the diffuser is not a blown diffuser
