Ultra Thrust Muffler for YS45
 

Can anyone tell me where to get an Ultra Thrust muffler for a YS45. I have checked around here in Canada but no one even heard of them so far.

Talk to Dave at Performance Specialties before ordering one of these for a YS45. They even quit making the YS45 adapter.
They don't work very well with the newer carburetor designs. The earlier carb would run the Ultrathrust pipe well, but not the newer ones. (about 5 years)
They will get a good top end out of your YS45 but the transition isn't good, and it has a tendency to get off the pipe. Then it is climb and dive time.
Hatori or Mac's work well.
