Outstanding parts, craftsmanship Brought my Honda RC51 to next level perfectly.

Works great

I live in a dense residential area, at the bottom of a valley, so it wasn't really fair to everyone else in the mornings. Luckily a nice chap from Yoshimura confirmed my model of exhaust would accept these silencers and they fit perfectly. There is still the deep throaty note but without the bark/bite but doesn't completely remove the overrun. I can live with that. Takes about 20 seconds to remove them
