Yamaha WR250F Exhaust Systems / Mufflers
Pro Circuit has a Complete Ti-4GP Exhaust System for your WR250F that will give you the power increase you desire, while meeting all AMA sound restrictions. Increased power from the bottom to the top end will make your bike easier and faster to ride. The silencer can is repackable by just removing the inlet cap screws and re-wrapping the core.
If a new head pipe is all you need, Pro Circuit has a Stainless Steel Head Pipe that will increase low to mid-range power. These pipes are hand-built from 304 stainless steel, giving you the durability and corrosion resistance that you need. This pipe also has a specially designed shape that gives more improved performance than a stock pipe.
FMF also has a slip-on exhaust for your use. Their Factory 4.1C SL Slip-On is based off of the Factory 4.1, but has a carbon fiber shell. The addition of this shell lightens the weight of this exhaust dramatically. The mid-pipe is still made of Titanium, and the muffler is the same as the popular Factory 4.1C system. This exhaust can be used with either stock or FMF headers.
