For a road going car, 2" would normaly be loud enough. Many with the 4A-G go to 2.25", which would sometimes sound good, and other times sound like a bee in a box, depending on mufflers. I am guessing 2.5" is a little extream, and loud. And loud will not always sound good if you have the wrong mufflers (cannons). I am planning a 2.25" system with mine, with resonator and muffler. I have 2" on my 3T-G and that is plenty loud enough, and sounds good.

Exhaust will not really help your car fun better (unless it is currently really really small). If it backfires it is probably running too rich. Or you can get bad backfire sounds if you have no exhaust, or the exhaust is too big with no resonator.

Some people put a rev limit of 9000rpm on the 20 valve. The stock 20v tacho goes to 9. But the stock rev limit is probably at 8200rpm. Some say that if you continuely run any stock 4A-G to 8500rpm you will do a big end or put a rod out the side. So if you want your engine to go a long time don't go over 8000rpm. If you know the tune is wrong, don't go over 6000rpm. If the tune is wrong, it will be very hard to get past 7500rpm anyway.
