I changed from a Fmf fatty to a Fmf gnarly and it's exactly what my Ktm 300 needed.Gave it a lot of pull from bottom end throughout the whole power range.

I really like how this pipe changed the power delivery on my bike! The quality is awesome and it was easy to install.
I purchased this pipe for a customer for a 06 ktm 200xcw and it was very poor fitting. The only way i got it to fit was adding really long bolts and bolting it up very loosely and was super hard to get everything lined up
This pipe paired with FMF spark arrester is a winning combination.
It smoothed out the hit and provides impressive low and midrange power without sacrificing top end.
Fast shipping. perfect fit.
Definitely a low end power type of pipe. The increased thickness of the metal was much appreciated.
Thanks guys for the fast service. I had a FMF Fatty on my yz250 thought the Grarly might calm it down some. Still scary fast lost a little top end.
Have been running a painted pro-circuit pipe and their silencer but wanted a spark arrestor as well. My pipe had various sized dents and dings so I chose to go with the FMF(it was in stock) pipe and spark arrestor silencer. Both arrived scratch free. Installed with no issues and look great, perform with no noticeable difference from the pro-circuit unit. I'm happy with the purchase.
I've had a couple different pipes on my 250sx and this is my favorite for trail riding, the low down torque is hard to beat.
Due to the variations that may come into effect when tuning an engine (i.e. pipes, intake, altitude, cams, displacement, standard or high compression pistons, etc.) we CANNOT offer jetting recommendations.
