Need Exhaust Rec's for my Setup

I have it narrowed down to the following:
See my Mod's, What should I go with?
Oh yeah, I also have Flowtech 1 5/8" Equal Length Shorty headers.

Dr. Gas 3" X-Pipe
MAC Pro Chamber

MAC Flowpath Cat Back
Spintech Sportsman Catback 2 1/2"
Spintech Pro Street Muff's

I live in Upstate New York & Emissions may become a problem within the near future.
Help!!!

I have it narrowed down even further but would like some feedback in regards to the following. Also I have a 5.0 GT Hatchback.

MAC ProChamber (2.5" or 3"???)
w/ MAC 2.5" Flowpath Cat Back

Or

Dr. Gas X (2.5" or 3"???)
w/ Spintech 2.5" Mufflers (Sportsmans or Pro Street???)

Anyone???
