www.jcmotors.co... This video on FMF 2-Stoke Exhaust Pipes highlights features on the Factory Fatty, Fatty, Gnarly and SST pipes. Get yours today at JC Motors - Where Riders Get Deals!
The type of sound that comes from any pipe is always a personal preference, but I can tell you that the best option for performance is usually to match the pipe with the header by brand. So I would recommend the FMF Pipe and FMF Silencer. I do like the sound of the FMF exhaust.
I own the Gnarly and purchased the SST last season and had them powdercoated in a crome like finish thats good to 2500 degrees. It keeps the heat in the pipe and promotes more exhaust flow. I use to own a Fatty but since the Gnarly and SST came out and 85% of my races are GNCC and other enduro races I had to get the power in the bottom and mid range. SST is like Flomasters principal, to get the exhaust gases out faster so the engine can scavenge more fresh air at a higher rate. Awsome products
Check your CVT roller weights.If they are too heavy your engine won't rev until you reach the speed your CVT will stop moving in.If too light you will be able to pop wheelies with no effort but you won't be able to get out of 60km.Try different weights or try mixing weights(ALWAYS cross-pattern).HINT:7g are closest to middle so you get both torque and speed but the ideal weight changes with every other change that will affect bike performance.Hope this helped!
It depends on what kind of racing you plan on doing and what your goals are as far as power delivery. In general the FMF Factory Fatty works well for MX.
The answer to that question will vary greatly depending on who you talk to and the type of riding being done. Having said that our customers have been really happy with the FMF Fatty.

i have a 1998 hasquvarna wr 250 with a gnarly pipe, that thing is mental it gave so much more power in low-mid but i can barely tell the difference between 5th and 6th probably be a good idea to get a different ratio sprockets but I'm not just because i don't want to ruin that mid range POWER!
sprockets will make a 100 percent difference. i run a stock pipe. 87 kx 250. its not worth the 200 plus dollars for any aftermarket pipe. thats my 30 years opinion.
good info on the fmf pipes, you helped me make a decision, im going with the gnarly for my trail riding on my '96 250 exc. the pipe bend is all dented in quite severely on my factory pipe, giving half the diametre over a 2 inch section, so i want the gnarly for the added thickness and low end torque. QUESTION: how does the gnarly pipe go in the top of the rev range? i hear that i peaks and drops off sooner, this is not a real problem for me, but it might take some of the fun out of my bike. (i just rebuilt the top end and power valves on the old girl and dont want it getting hot by not being able to breathe)
ANSWER: Yes it will drop off sooner. 2 stroke exhaust systems are always a give and take. It will breathe just fine though. Keep in mind you could also play with your gearing a bit to. Once you get the pipe if it feels like you have ton's off the bottom end but it sign's off a bit soon on the top try going 1 or 2 teeth smaller on your rear sprocket to balance it out.
Yes, the FMF Fatty and Factory Fatty will fit your motorcycle. Go to the JC Motors web site and click on exhaust on the left side of the screen it will take you to our exhaust page. From there you can enter your motorcycle year, make, model and see exactly what exhausts will fit your bike. Ride safe!
You guys need to expand your inventory. I just checked for a pipe for my Dad's RM250 and all you have is about 10 to choose from and they are for KX250 05-07, KTM125s, and a bunch of smaller CC bikes.
I'm looking for power everywhere on my YZ250. So the best choice must be the Fatty, but what silencer would be best. I don't want to kill the high RPM with a shorty.
i have an 03 yz250 with a turbine silencer, i am debating in between the s series and fatty pipe. i ride out at hungry valley and am looking into some freestyle, i also ride in sand pismo glamis so i need an overall pipe that is going to let me have more overall power. What would you recommend?
what silencer would be best for my kx 85, I currently own a fatty pipe and stock pipe, I am into motocross and racing. I heard pro circuit R-304 silencers go well with the fatty but not too sure.
yeah I got the fmf powercore 2 and gold series on a 2001 rm250 I did not notice any thing in the mid or lower BUT MAN that power band I cant keep the front wheelie down I gotta say it did help but some reason I like the stock muffler at a idle better but the fmf in the high rpm does sound sick
hello i have a question to ask you i have a 2 stroke yamaha bws and i just got a gianelli pipe and from 0-65km i role very slow but once i reach 65 i get this wierd "power band" and my scooter just takes of all the way to 80 and probably more but sometimes on a flat surface my scooter cant reach 65km because it takes alot of time do u think you know the problem with my pipe??? cause my friend has one and at 60km his "power band" kicks in i would really love to hear from you thankz!!!
hey i have a KX85 and i rode a Yz85 that sounded really good it had a nice clean sound to it and it had a good powerband and it was a fmf pipe with a procircuit silencer what do u think sounds best
I would recommend checking that the radiator and mounts are not mis-aligned or damaged. Then I'd suggest calling FMF at their corporate number 310-631-4363.
The 96 YZ250 I got a while back has a Platinum on it, I'm hoping I can get more bottom end out of the bike. I hear opinions both ways on the Platinum giving bottom end, so does anyone have the real scoop on it? Dyno sheets that tell once and for all? FMF doesn't make the Gnarly for 96, but if I made a 97 Gnarly fit just how much of the top end would I loose????
I have a KDX200 with a platinum, it has good low end and great midrange, not much up top, and a flatspot just off idle I am trying to rejet it , ... I'd like to try a Gnarly, it's very tight technical trails around here
I found out a while back that my powervalve wasn't working because the linkage screw was backed out. Lots of bottomend now, but I did the Gnarly conversion before I found that. lol
I ride a 1990 kdx200. I would like a gnarly pipe for it, but the only aftermarket made for it is a fatty pipe. Would a fatty pipe work good enough for tight single track.
Well first off your bike is not built for track, I used to own a 2005 KDX 200 with a Fmf Gnarly Gold series pipe and a Fmf Powercore 2 Muffler. Now I ride a 2004 Kawa KX 250 mx bike with the same FMF setup.

😂 Haha😂
"Aff-Am-Aff"- that guy.
The FMF Shorty Silencer works well with the Gnarly and will give you plenty of bottom end.

tell dude that fmf has been around since 73. not 79.....

i actually have the SST pipes on my Banshee. Talk away a top end rocket! Love the FMF products. Great Job
The FMF Fatty pipe is the best overall pipe around for the riding you are doing. Hands down.
Check your CVT roller weights.If they are too heavy your engine won't rev until you reach the speed your CVT will stop moving in.If too light you will be able to pop wheelies with no effort but you won't be able to get out of 60km.Try different weights or try mixing weights(ALWAYS cross-pattern).HINT:7g are closest to middle so you get both torque and speed but the ideal weight changes with every other change that will affect bike performance.Hope this helped!

I Run Toomey T5's In My Banshee AMAZING!

Go with the Fatty pipe and either the Powercore 2 or Turbinecore 2 if a spark arrestor is needed.
I'm looking for a pipe for my bike its a 2007 kx125 i race motocross and abit of endruo what would be the best pip please help me

Yes, it should have an indent where it bends around the frame.
it will, i had a bills header to a fmf power core 2
Nice Honda comparisons!

blew a hole the size of a tenis ball in my pipe about 30 mins ago on my Peugeot xps 50 had the pipe since 2008 so there quite good
I'm looking for power everywhere on my YZ250. So the best choice must be the Fatty, but what silencer would be best. I don't want to kill the high RPM with a shorty.
Affff m afffff pipe
Bring back the Fatty for the CR500!
i love af am af
Tommey's #1 Pro Circuit #2 FMF #3 I ride T5's on my banshee and boy o boy

Please respond I have a fmf turbine core exhaust pipe it I knew a fmf power band pipe the big one which one should I get
afamaf
Asastee
your so right lol afamaf
I wish they had an sst pipe for lt250r cause I ride the high rpms most of the time and that's were I want my power but oh well
i have an 03 yz250 with a turbine silencer, i am debating in between the s series and fatty pipe. i ride out at hungry valley and am looking into some freestyle, i also ride in sand pismo glamis so i need an overall pipe that is going to let me have more overall power. What would you recommend?
dang I feel old I raced for fmf in the 70s and the bike frames were before the pipes. DG was first I think
what silencer would be best for my kx 85, I currently own a fatty pipe and stock pipe, I am into motocross and racing. I heard pro circuit R-304 silencers go well with the fatty but not too sure.
Flying Machine Factory
you did not say any thing about fmf gold series let me know the specs on that
The FMF Fatty pipe is their gold series pipe.
i have a Gold Series Fatty pipe on my Kx250 and i love it, gave me better response on trails but still pulls very strong on straight sections
yeah I got the fmf powercore 2 and gold series on a 2001 rm250 I did not notice any thing in the mid or lower BUT MAN that power band I cant keep the front wheelie down I gotta say it did help but some reason I like the stock muffler at a idle better but the fmf in the high rpm does sound sick
i have a 93 kx 80 what pipe do you recomend for me?
What was the name of the one you said was the best for motocross riders and is used on the banshee.
So how can I move my radiator cause my fmf sst touches the radiator. And I got a yz 250 I got a vid on my channel of it
i have a fmf power core2 and a fatty gold series
hello i have a question to ask you i have a 2 stroke yamaha bws and i just got a gianelli pipe and from 0-65km i role very slow but once i reach 65 i get this wierd "power band" and my scooter just takes of all the way to 80 and probably more but sometimes on a flat surface my scooter cant reach 65km because it takes alot of time do u think you know the problem with my pipe??? cause my friend has one and at 60km his "power band" kicks in i would really love to hear from you thankz!!!
is it possible that the 4-stroke dirt bike can use the 2-stroke exhaust pipe? what is the prblem if not? im confuse.. thanks
i think the yellow powerband works best
hey i have a KX85 and i rode a Yz85 that sounded really good it had a nice clean sound to it and it had a good powerband and it was a fmf pipe with a procircuit silencer what do u think sounds best
Gnarly seems like the more practical choice for me
af am af 😂😂😂
so is there no real difference between the fatty and factory fatty other than the finish?
is the fmf fatty supposed to have a small dent in inner part of it? Please answer!
i have a 2004 kx 85. what would be the best for racing for my bike
when you put a pipe on a 2 stroke is it necessary to reject the carb?
I would recommend checking that the radiator and mounts are not mis-aligned or damaged. Then I'd suggest calling FMF at their corporate number 310-631-4363.
thanks for the video
Is the sst good for desert riding because its mid to high end power
Unfortunately, it doesn't look like they make an exhaust for the Yamaha RT100 at this point.
hello i have a honda cr 250 that i only ride on week ends wat pipe do u think i would need?
And ballistol to keep it clean
muy bueno
whats better for the dunes? cr250
that exhaust on the left what bike is it from
aSaST pipes look cool
Do they make a pipe on a yamaha rt100?
This guy should do the aff-lack commercials
what about fmf nolan pipe
Factory Fatty ftw!!!
The 96 YZ250 I got a while back has a Platinum on it, I'm hoping I can get more bottom end out of the bike. I hear opinions both ways on the Platinum giving bottom end, so does anyone have the real scoop on it? Dyno sheets that tell once and for all?

what would you recommend for a 2000 Suzuki rm 125
that pipe on the far left, what bike is it from ?
do you stock gnarly pipes for a yamaha wr200r 1993?
I ride a 1990 kdx200. I would like a gnarly pipe for it, but the only aftermarket made for it is a fatty pipe. Would a fatty pipe work good enough for tight single track.
Well first off your bike is not built for track, I used to own a 2005 KDX 200 with a Fmf Gnarly Gold series pipe and a Fmf Powercore 2 Muffler. Now I ride a 2004 Kawa KX 250 mx bike with the same FMF setup.
whats the best pipe for a ktm 65
correct
either a 500 or a banshee
The fist pipe I think is for a blaster and the second is for 85/100 kx I know that
and stronger clutch springs
