Do yourself a favor and look on E-bay, I just bought a brand new full Yosh RS-3 for $345 !!!!
Jardine pipes are priced very competitively, they make nice stuff too. I had a Muzzy on my F4 last year, I only had the bike on the track 8 days and the pipe started to fall apart. I wouldn't recommend a Muzzy to anyone....
