FMF Gnarly Pipe


The FMF Gnarly pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. When looking to add 4-stroke tractor like torque to your 2-stroke machine, and you need a pipe to withstand the harsh elements - this is the pipe for you. Strong and rugged, the Gnarly pipe's aggression dishes out handfuls of torque and bottom to mid-range pull needed for late model machines and that traversing the gnarliest of terrain. That's why FMF is proud to call it the Gnarly Pipe!

  • Finished in FMF's trademark nickel plating that's been copied by everyone making it the most imitated expansion chamber in the world
  • Big bottom-end power is ideal for hilly and tight terrain
  • Fabricated out of super-strong 18 gauge steel to absorb hits in the gnarliest terrain
  • O-rings included
  • Made in the USA

Answer Question

Will this fit my fmf silencer on my 1998 cr250r?

As long as it is a standard FMF silencer either Turbinecore or Powercore and not an older SST series muffler. Those were proprietary to the SST series headpipes.

By Staff
Answer Question

Will the Gnarly pipe fit the stock silencer on my 2017 300 xc-w?

FMF pipes for 2-stroke models can re-use the original silencer. You would have no issue installing this Gnarly head pipe with a factory KTM silencer for your 2017 KTM 300 XC-W.

By Staff
Answer Question

Does it come with all the hardware

FMF pipes require that you re-use the OEM exhaust springs and O-rings in order to complete the installation. In the instance the original equipment on your bike isn't in the greatest shape, we do have FMF Pipe Spring & O-Ring Kits for many models so as to make installation of the new pipe as easy as possible.

By Staff
Answer Question

Does this come with o rings and springs?

All FMF pipes come equipped with the O-ring gaskets to seal the pipe to the factory exhaust port on the stock cylinder head. As for the springs, you are to re-use the OEM springs when installing an FMF pipe as they are no included.
