From memory, there is a 90 degree angle directly from the turbo pointing down, then another 90 degree to level the pipe out. But making a downpipe without using the car as a template is a really bad idea. Very hard to make it fit.

Racing beat shows you a pic of a FC turbo DP. I would not build off this picture, plus its only $125 dollars. Not sure you can pay to have someone else make a better DP for that price.

Aaron Cake is correct, it's essentially two 90 degree angles. You will want to buy the flange from mazdatrix, it's likely that whoever is doing it for you won't have it.

It only cost me $40 - $50

That's got to be the craziest thing I've ever heard, and I can't think of any logical reason for it. You don't build an exhaust on an internet forum, you build it on the car! If you want this to fit properly I highly recommend you either find another exhaust builder or buy an aftermarket one.
