I think you'll be fine with changing the downpipe transitioning from 2.5 to 3 inch. It creates a slight vertex vaccuum that can assist in pulling exhaust gases along as it forces it out..

Re: (The Shodan)

at higher psi you will notice more of a difference.

i went from a 2 inch to a 3 inch and gained almost 30whp..

Is it possible to keep the A/C with going to 3"? I was looking at my 2.5" and it's a tight fit. Ditching A/C in AZ is not an option
