Got it and installed it today, took about 15 minutes. All I can say is WOW. I got the race baffle, and this thing barks. Perhaps a tad louder than I expected, but it does sound impressive.

I cannot tell if it effected performance at all, but it pulls strong all the way to redline. To me it seems like it might not be as smooth as the stock pipe, but I think that is because of the noise. Any pops or bubbles or sounds that I am hearing now would have been softened with the stock pipe. Not that it is running rough, but the stock pipe did mellow things out, so I am hearing sounds that I was not hearing before.

Some pics with the new pipe and the black wind screen:

Oh, and props goes out to the guys(and Megan) at PipeCity. Awesome prices, prompt service and I am very pleased with them.

Next mod will be the 520 conversion, but I will hold off on that for a bit, probably until I need new tires. The shop will have the wheels off anyway, so it will be the perfect time for them to swap out the sprockets. From there, I don't know what else I can do other than start swapping pieces out for Carbon-fiber in order to lighten the bike up over time.
