ATS uses 2.25" ID pipe before the turbo which turns into about 2.5" ID for the up pipe after both manifolds come together into the up pipe.
Small pipe diameter keeps the exhaust moving fast so it spools the turbo faster.

So you need to run 2.25" ID pipes from each manifold to the turbo exhaust entrance flange.
With the way the manifold pipes clamp on, 2.25" ID pipe is the biggest thing you can get on them anyway.
