Get This Pipe!
Installed on a 2013 KTM 250 xcf-w that ran flat nothing after 1/2 throttle. Installed pipe it now has punch all through power band almost as fun as a sxf! If you own a xcf-w uncork your bike this pipe is best modification for exhaust. It's night and day on power delivery!

Needed a SA
This gave me a bit of performance boost and a SA to be compliant. Easy to remove SA for when I convert to snowbike with the Timbersled kit. Great sound!

The pipe its self works & sounds great, just a little rough around the edges
The joint doesnt fit cleanly to an oem header pipe, it requires a sealant to close the exhaust leak. The manufacturers sticker was torn off and the end cap finish around the exit tip was a little rough. Its almost as though it was a factory blemish pipe

Solid
Quick, easy, and not complicated assembly. Provides a nice tone. It should be noted this does not require or come with a clamp to the header.

Great pipe for the money!
I was looking for a spark arrestor for my bike and nothing I found was all that great so I decided to try this pipe and so far it's really good. Sound is awesome, definitely louder than stock but not so loud you can't stand it. Installation was easy and fits great! The spark arrestor is a piece of cake to change when the time comes. I would recommend it for a cheaper alternative compared to the high cost of some of the others.

Hi want to know will this fit on the stock header or do I need to buy a fmf one? On a 2011 ktm 250 sxf
Danny B on Jan 1, 2017
BEST ANSWER: This should slide right on to your OEM header.
Is the S/A removable?
Alex M on Nov 22, 2016
BEST ANSWER: Yes the S/A is going to be able to be removed.
Does it also come with a "quiet" insert or just a spark arrestor insert?
A shopper on May 1, 2017
BEST ANSWER: I believe it's a spark arrestor insert.
Looks like a piece of screen
Not sure exactly what your looking for but I don't believe you'll be disappointed !
Is it a "straight thru" design?
A shopper on Apr 26, 2017
BEST ANSWER: Yes it is. Has screen insert included. Much lighter than stock fe501s part. Throaty and a ltitle loader. Power gains everywhere. Easiest mod to install
Does it come with the spark arrestor installed? If not, what does it take to install it? Will it fit my 2016 YZ450f stock exhaust system, frame and side panels without modifications?
Gary J on Apr 7, 2017
BEST ANSWER: Yes it comes with a removable spark arrestor. It's a screen cone type that's held in place with a small allen bolt. Yes, it should fit your YZ without any modifications. All the newer YZ/WR platforms are pretty much the same set up. Mine fit just fine. Also note you will no longer use the stock pipe clamp coming off the header, you will need to apply some high-temp silicone to seal the joint.
I have a 2017 kx250f while i need any custom tuning to my machine so it doesn't hurt it?
A shopper on May 22, 2017
BEST ANSWER: The kx 250 is fuel injected. I do not think you need to tune your bike so it doesn't hurt it.
Is the spark arrestor USFS approved?
Jason P on Jan 27, 2018
BEST ANSWER: Yes. There is a placard on the end of the muffler.
I was told that my there wasnt a fmf pipe that would fit my 2016 Husqvarna FE 450. Can anyone shed some light on this?
John B on Dec 30, 2016
BEST ANSWER: Call FMF and talk to their support team, they'll take care of it all????
