Magnaflow Y-Pipe

Hello. In reviewing some of the suggestions on the Overkill site, I noticed a short post on removing the restrictive Y-Pipe on 10th Gen Impalas - along with eliminating the 3rd Cat.

Has anyone done this? if so, what inlet/outlet size Y-Pipe did you go with (the Magnaflow site shows 5 choices) and if you remove the 3rd Cat will it trip a "Check Engine" light? Cause you not to pass inspection?

Thank you.
