FMF Racing Fatty Pipe Reviews

Does what it says

Most people replace their two stroke pipes because they are dented up and if they replaced it with a stock one they would notice a difference in power compared to their dented one, so when they say how great their new pipe is,they really don't know.Unless the stock design is really bad,you are usually just moving the power around,so you lose bottom for the top and vice versa.So I replaced the original condition pipe on a 1998 Suzuki RM 125 with the FMF Fatty.The fit was right on with the stock muffler.With the stock pipe,it had a decent pull for the bottom(for a 125) that went to a stronger midrange and pulled to a decent topend. Didn't really feel any different on the bottomend with the Fatty but it did pull harder in the midrange and went on to a longer topend pull. It pulled each gear harder and longer which really helps out in the hills and heading to the Big Jump! For $249.99 and on this bike you get a lot of bang for your buck!

Came with an old FMF Gold series fatty. 

5 stars

fit is mediocre, which is strange because every fmf product ive ever owned has fit better than stock. Power is ok pulls for a long time, lots of over rev, very flat down low, small hit in the mid range.
