Unless you plan on getting some high compression pistons, I wouldn't get the 2.5 inch piping, nor would I get aftermarket IM or TB, and stick with a mild cam like OEM ITR cams. 2.25 is a bit on the small side for a GSR with upgraded cams. 2.36 sounds like it'd be ideal for what you have planned, unless you'll be doing a piston upgrade, then I'd get the 2.5 piping. Be sure you get a muffler with 2.5 inch piping if you do get the 2.5 exhaust.
I gave this thread a better title, cuz I agree it's not just another exhaust thread. lol
