Oh yeah, I guess I should mention why I'd do such a thing. People do it to achieve a better sound... a better exhaust note. The sound coming from the cylinders won't mix so apparently you get a more distinct sound. It seems logical but I won't know for sure until I fire 'er up (that ain't gonna happen anytime soon... my bike is all torn apart).
Anyway, it's said not to do it if yer running restrictive pipes 'cause the crossover allows for better breathing. But if you have open pipes the breathing thing becomes a non-issue. There's plenty of reading on the topic in the following link, which has links that lead to more info and so on.
