Piping bigger or stock?

[New2Dsms]

Ok so let me get this right the stock exhaust piping is a full 2inch diameter inside? and a 2 1/4 on the outside?(Correct if im wrong) So my question is should i make my piping any bigger if i will have a cai,header,high flow muffler and nos...I also plan on running a straight pipe.

Do 2.5 (inner diameter) MANDREL BENT piping. You will see noticeable gains and throttle response.
Your dimensions sound right. Good luck man.
