If you are not camming then changing to bigger exhaust wont net you much gain if any.
3" will definitely be louder.
Are you going to change your cats as you could fit 200cpi metal cats for better flow and still meet emissions.
Mine has tiny cam and heads and nets 299rwkw through 1 3/4" shorty headers, high flow cats and stock cat back.
I do lots of highway cruising with our mothers on board and wanted it quiet but still sound like a V8 when you are up it.

VZ Clubsport M12
I have a VZ clubby manual. She has VY2 hsv headers (1 3/4inch primary). Twin 2.5inch system all the way through - decats and two hotdogs (coby) each side. Dynod at 310rwkw @ 6300rpm. Has OTR, VCM 11 cam and supporting gear. I haven't seen a need to go to 3 inch as yet. Plenty of power thru the Rev range. I like the 2.5inch as not too loud. At 100kph can hardly hear it.. but still has a dam good note at idle and drive around town.
