Product Information

FMF GOLD SERIES Fatty Pipe

The staple of FMF’s two stroke line, the Gold Series Fatty Pipe broadens power across the whole RPM range. Suited for both motocross and woods riding, the Fatty gives a healthy snap off idle, strong mid-range and a longer top end pull. If you ride a little bit of everything with your dirt bike, the FMF Fatty Pipe is a great and very tough choice.

Features:
  • Computer designed and dyno tested to focus power gains where each machine needs it most
  • Every pipe goes through the Tru-Flo stamping process to ensure quality performance and optimum fit
  • Different pipes for selected models allow fine-tuning of a bike's powerband- Fatty pipes offer better bottom and top power
  • Constructed of 19-gauge steel with a nickel-plated finish

FMF gold series fatty

I put this on my CR 250R to replace my stock pipe, it fit fine and only took like 15 minutes to put it on along with the power core silencer 2. Overall I'm happy with the product and the price wasnt too bad.

Feel The Power

It adds power everywhere, but it keeps the power smooth. I will be getting one of these for all the bikes to come. The fit isn't perfect on my 250sx, but it's good enough.

Able to lug a lot more

After putting this and a Turbine Core 2 on my 2001 CR 125 I noticed immediately the change. I went from a REV pipe to obviously this one. With this pipe I was able to lug it a lot more. The power band was smooth, I didn't have to rev as much so it wouldn't stall out. The only thing I did after getting the pipe was adjust the idle. Great pipe all in all! Greatly recommend!

Seems to work well, the finish could be a bit nicer and the welds could look better, but other than that it's good.

Fatty Pipe on RM125

My 13 yo boy put the pipe on. We also got the Fatty silencer and then had to rejet the bike, which really was no problem. We bought the jets off eBay and changed the clip on the long needle ourselves. You have to take the top of the carb off to do that, but no big deal. Darren says the power increase is very noticable; he literally flew down the street. As always shipping was quick and packikng was good with this stuff.

Fatty+Shorty= Way faster bike

I put a fatty and shorty on my 09 KX100. It pulled so much harder and the throttle response was like cracking a whip. it is an awesome pipe. If you are buying a pipe for a KX100, get this combo.

nice

I bought a 01 CR80 with it on. Only drove stock 80 but I like the way the pipe sounds. Gives my powerband a lot more power. Would recommend pipe for tracks, trails, or even around the house. Fun.

Fatty Pipe

I have been using a Gnarly pipe on my 200 EXC. While good in tight, technical terrain, the Gnarly kills the top end on that bike. I ordered a Fatty for a 200 SX and WOW, what a difference. There is no noticeable loss in bottom end and the mid to top gain is huge. The only modification needed is to reverse the front pipe mount to clear the wider body of the Fatty. If you want to wake up your 200 and put some hit back in the power delivery, try the SX Fatty.
