You can buy one direct from Tom at Biohazard Cycles in Florida for around £470, he charges $75 delivery and is helpful with charges etc
Hello mate don't want to pee you off but before you purchase look through the forum in regard to the Taylor made exhaust There's not many Fourm members on here that rave about them
Just fitted one to my mates RR8, looks the dogs bollocks, maybe not the best quality can but is the smartest.
A friend has had one since 2008 and it has only recently started blowing a bit, cannot really complain for 5/6 years regular use. I would swap my Yoshi R77 for one and I love the sound of the Yoshi.
