3L, longer duration cams (280ish), ported head paying special attention to the flow through the valve seat and exhaust port with general smoothing out, adjustable cam gears, at least a fuel computer and a custom intake. Probably want to take it out to 6000-6500rpm dpeending on cam setup.

sounds like a nice plan 
i would hazard a guess that you'd want to go closer to 3" or at least 2.75" diameter, all the way from extractors back. you may need to experiment with different muffler/resonator setups to find one that sounds to your liking..... give a few exhaust shops a call to see what they'd recommend, and don't let anyone tell you that you need backpressure to work properly 
as was said before, it's the extractors that tune the motor, and the exhaust is there to quieten things down and kep the gases away from the passengers.....
if you ar ein ydney (or can call from work ) give Australias Best Muffler Service a call (canterbury road, sydney) a call, as they seem to give prety good advice.
