So far it sounds good, good luck if you have any questions ask

Dude dont screw the balance up on your car when you lower it. You can make the car unstable and a bitch to drive

Well I dont mean to bash but there are 2 things that I wanted to ask before you run this thing first is the what is the exhaust size of the turbo that you are going to run also what kinda Hp. are you looking to make? Because thermal expansion can fracture the header bolts so over size those also the flang can warp under high temp. this will break welds cutting the flang will help with this problem.. this is for high Hp. apps.
Smooth, constant velocity is what you want
I do have one other question what is the thickness of your tubeing it could be a problem.
As for the down pipe figure 10% larger than turbine outlet diameter. also when you weld the down pipe flange weld in 1/2" increments that will help. I hope that helps you out
