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