Details

    KTM’s SXS Factory Silencer with Spark Arrestor takes the power characteristics of the standard SXS Factory Silencer and puts it into a spark arrested variation that is USFS approved for any regulated riding area.

    With the spark arrestor the silencer still produces factory levels of power and performance, but you won’t be limited to closed courses or race tracks. And that’s especially handy since the SXS delivers well-rounded power throughout the rpms which makes it perfect for trail, enduro, and cross country riding where usable power is key.

    Construction is the same as the standard SXS with premium aluminum alloys and stainless steel making weight much less than stock, and you get the same removable hardware that makes maintenance/repacking a simple job.

    Specs:
  • USFS approved spark arrestor
  • Maximizes power across rpm range
  • Made in conjunction with FMF for KTM Powerparts
  • Lighter than stock silencer
  • Removable hardware for easy servicing and repacking
  • Delivers factory-like performance
  • No specialized tools needed for disassembly
  • Deep works-like exhaust note
  • Cues taken from FMF’s Powercore 2.1
  • Extruded, anodized aluminum canister
  • Integrated mount(s)
  • Formed stainless steel end caps
  • Mandrel bent stainless steel stinger
  • Premium packing meets KTM standards for performance and durability
  • Made 100% in the USA

KTM Factory FMF silencer
It's not much longer than the FMF
shorty that I use for MX, and goes on just as easy. Ot s[reads put the power more that the Shorty does, and sounds great.

Decent
Wanted this one for the spark arrestor. Starting off with install. I was mating it to a DEP armored enduro pipe, and it was rough installing it. Got it to work, loosened the pipe bolts, let everything free float, and sprayed WD40 on the slip on point. Slipped in far enough to get rear bolts in after some muscle. My chick held the front of the bike as i pushed the silencer forward. Next, the run time. Sounds amazing on my 300, and looks killer. Shorter than stock and forest legal. Only issue i had is the bolts backed out, and silencer dangled. When that happened i lost the inner rubber bushings and outer washers. Went to homedepot and replaced with some M8 bolts and washers and a junk chain guide pin bushings. MAKE SURE TO USE LOCTITE on the bolts. Did that, never had an issue. And torqued to KTM book first and second time.

must have for ktm
Sounds great on my '15 300xc. Seems to be a little louder than stock with much more tone. The power difference is slightly noticeable with more pull throughout. Overall it looks great I really like the black, and is a decent price.

great silencer
Don't know why an enduro bike doesn't come stock with one of these. Small, lighter, better looking, better performing than stock.

Looks and works great
I was expecting better quality from this especially since it was more money then other silencers, but for some reason their was oil leaking out of places it shouldn't have been but after a couple rides the dried up oil sealed it and stopped leaking in those areas. And I'm surprised that the KTM power parts sticker is actually just a sticker that's poorly pasted on, and the warning label that nobody cares about is a permanent plate. Other than that it was easy to install and looks really good and it feels like I get better performance. And I got more confidence riding that I won't burn a forest down anymore with the spark arrestor.

FMF
Opened the power up a bit. We bought it b/c we needed a Spark Arrestor for a National Enduro. (Passed tech perfectly)

Looks great on the bike and is much shorter than stock (it kind of peeks around the side panel now)

FMF is made in the USA and supports a lot of our series. Good company to support with a good product.

ITS BROWN???
I have had this silencer for a year, it sounds good and looked good. after running the bike hard with extensive hill climbs wide open between 40- 70 mph for about 2 minutes of full load the silencer got so hot that it has faded the black anodizing to a almost metallic but definitely BROWN color, the stickers have burned and shrunk. sounded good though! might do a brown theme on my bike now??

Does this silencer come with the rubber grommets to mount the silencer to the subframe?
Diane R on Apr 4, 2017
BEST ANSWER: No, you will re-use the factory grommets or you will provide new ones for yourself if your existing grommets are in bad shape
The silencer works well it adds a little powerl and loses some weight and it is fairly quiet I am happy with mine on my 2016 KTM 300 6days
Is this Cali compliant?
A shopper on Oct 2, 2016
BEST ANSWER: Based on the information that I found, it is compliant. Here is the CA law found in ohv.parks.ca.gov: "CVC 38366. (a) Notwithstanding Section 4442 of the Public Resources Code, and except for vehicles with mufflers as provided in Article 2 (commencing with Section 27150) of Chapter 5 of Division 12, no person shall use, operate, or allow to be used or operated, any off-highway motor vehicle, as defined in Section 38006, on any forest-covered land, brush-covered land, or grass-covered land unless the vehicle is equipped with a spark arrester maintained in
effective working order.
(b) A spark arrester affixed to the exhaust system of a vehicle subject to this section shall not be placed or mounted in such a manner as to allow flames or heat from the exhaust system to ignite any flammable material.
(c) A spark arrester is a device constructed of nonflammable materials specifically for the purpose of removing and retaining carbon and other flammable particles over 0.0232 of an inch in size from the exhaust flow of an internal combustion engine or which is qualified and rated by the United States Forest Service.
(d) Subdivision (a) shall not be applicable to vehicles being operated off the highway in an organized racing or competitive event upon a closed course, which is conducted under the auspices of a recognized sanctioning body and by permit issued by the fire protection authority having jurisdiction."

See section about qualified by USFS which this is certified.
Does this have a screen or is it a turbincore?
Todd M on Oct 10, 2017
BEST ANSWER: Turbincore, I have been pleased with mine so far. A fair bit shorter which looks really nice 👍🏼
What packing do I buy to re pack this exaust?
derrick d on Feb 28, 2018
BEST ANSWER: You can use basically an packing, but the FMF repack works well in it since its an FMF built muffler for KTM. Here is RockyMountain’s part # for the packing: 1563740001
Is this Cali legal?
dustin s on Oct 2, 2016
BEST ANSWER: Not sure what Cali's restrictions are but it has the Forestry stamp on it with a Spark Arrestor. That's what is required by us in Florida to race in the "woods".. They may have a DB requirement but most 2 strokes are well below the noise limit as long as the packing is in decent shape.
Does it fit 2017 models as well ?
I own Exc-w 300
amit e on Sep 10, 2017
BEST ANSWER: Unfortunately, this will not fit your machine. I'm sorry for the inconvenience.
