Expansion chambers

[beerbunny]

Hi.

Does anybody have any experience of this expansion chamber: - http://pieces-mz.com/sport-exhaust-pipe ... -1167.html on a TS250/1? I'm guessing that if it has any effect on the power characteristics, it'll be to shift the power band to a higher rev range. Also, how noisy is it?

Any comments would be appreciated.

Cheers,
