Default What diameter cut-out?

What diameter cut-out do I need for the stock piping if I am going to get the cut-out installed under the rear seats in the i-pipe? I though 3' but the piping doesnt quite look to be 3'.....any help is appreciated.

stock I-pipe is 2.75" inside diameter, which makes it sometihing like 2.85" outside, therefore the 3" iinside diameter cutout is the way to go.

any competent welder can make up the difference
