FMF Racing Gnarly Pipe Item # 135526
Description
The FMF Gnarly pipe focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain.

Strong and rugged, this aggressive pipe dishes out handfuls of torque and bottom to mid range pull needed for late model 200cc through 500cc machines and the rigors of the off road domain.
Features:
- Nickel plating is an FMF trademark and has been 'copied' by everyone making it the most imitated expansion chamber in the world
- Super strong 18 gauge steel construction makes it GNARLY!
- O-Rings Included

Great for tight woods riding, enduro.
I race enduro's in Ontario and this is my pipe of choice. It provides great bottom end for lugging it through the woods, through mud, up hills etc, but as a trade off it tops out sooner than other pipes and sometimes I wish I had a bit more top end before having to shift. The heavy gauge material is nice if you're riding in hazardous areas with lots of logs and rocks to ding up your pipe - but it's a double edge sword; these pipes are harder to repair back to original condition once they get banged up. They don't quite go back to the original shape like the thinner ones. Fit is bang on. Easy to install. I believe they come with O-rings installed but not springs.

Smooth power delivery, more torque exiting corners
I bought this pipe about a month ago. My original one was completely trashed. It made my bike wake up a bit faster and definitely provided more torque in the lower revs. It fit good had to trim about 1/2" off the end so my silencer bolts would line up, no big deal.

I changed my smashed OEM pipe at the same time with carbon dual stages boyesen reed valves and Ho boy! Does it gave it the kick I always taught was lacking. No more flat over-rev, nice kick at midrange and the tractor-like low end was better than before. Definetly the pipe to put on a KDX220R, I borrowed a Woods pipe instead of this Desert before buying and it was very deceiving power-wise. Only negative points are my bike is louder than before with the OEM muffler and the pipe larger bell diameter had me burn my leg a few times.

Well built, a touch more low end
I have had two of these on my bike, in between I switched back to the stock pipe and could feel that the low end touch that this pipe adds was gone.

Great pipe
I have not noticed a difference in power but I have also not tuned the carb. I love the sound. The sound is definitely worth it!

Fits Great, Great Performance!
Installed on a 2015 KTM 250 xc. Had a fit issue, but it wasn't the pipe, the mounting tab was slightly bent on the frame. Immediate and very noticeable change in power characteristic of the bike. Can easily lug up a hill slowly without clutch, but definitely noticed less over rev at the top over stock pipe. Perfect for trail riding!

Love this pipe
Great low end boost and torque. I am really pleased, it signs off sooner than stock but great for woods

Still waiting for silencer
The pipe I received was here ahead of time and worked great but I still haven't got an email notification regarding the silencer that go's with it. If someone would update me on that that would be great
