Yamaha YZ85 Exhaust Systems

FMF Racing has some fantastic exhaust pipes for your YZ85. Their patented SST pipe gives you higher mid-range pull, greatly extends the over-rev, and will also sharpen the off-idle throttle response. FMFs Tru-Flo stamping process guarantees a snug fit, as well as maximum performance. Lastly, they have been chrome plated for a sweet look and longer life.

If you are looking for more power across the whole rpm range, FMF’s Factory Fatty is for you. The Factory Fatty gives you the “factory” look, while increasing your horsepower and torque. The body has been produced using a lighter 20-gauge steel, while the header is 19-gauge.

FMF’s Gold Series Fatty pipe is manufactured from 19-gauge steel and has a nickel-plated finish. This sleek looking pipe increases power across the board, also including better throttle response and over-rev. The Gold Series Fatty also goes through the Tru-Flo stamping process, so you know it will give high quality performance and fit your YZ perfectly.
