Seems to me that even by the time the Gen2 was created that the Exup had started to have its day with Yamaha....perhaps because they sound so bloody annoying to keep clean and working well and well i dont see exups being used on any of the new range of bikes so obviously they've figured out other ways of improving exhaust flow throughout the rev range.
Easiest way to go fast........don't buy a blue bike
