I would definitly do a rev pipe on the 220. Because of the porting differences between the 200 and the 220 the pipes act differently. A rev pipe on the 220 basically gives you better power everywhere, with more revs up top. The torque pipe gives you some more down low, but then falls on it's face like the stocker, some people say it runs out of steam even sooner. I have the rev pipe and would not have it any other way. Riding with a stock pipe it seemed like I was always shifting because it would run out of revs so quickly. Now I can pull a gear much longer and spend much less time flapping through gears.
I've had my bike ported, head recut, carb bored, added a pipe, silencer, and reeds. I know it lost low end, but it pulls much farther into the rev range now. I went up 2 teeth on the rear sprocket and still gained over 9 mph top speed over stock because of the extra revs. My buddies that ride my bike still think it's a real torquer. It can pull any hill in 2nd with a twist of the wrist, and it you dab the clutch a little it will pull almost anything in 3rd, although with a lot of spinning.
I ride everything from wide open sand trails to tight rocky / muddy / hilly / thorny / tree-root-infested trails. The bike works great for me. With the porting it does take a more aggressive riding style in the super tight stuff, but that's how I ride anyway (till I get a little older).
