GasGas and the FMF Q silencer

All I can say is amazing.

Bolted on a new FMF "Q" spark arrestor to an '07 EC200 this weekend for a District 23 (Minnesota) Hare Scrambles and got sound tested at 85db!!

The sound checking crew thought there was something wrong with their meter and tested it again to be sure. Sure enough 85db!

Of course sound meters can be out of calibration and I'm not declaring that an FMF "Q" spark arrestor will get you down to 85db but I think FMF deserves a "thumbs up" for making a great product that more than gets the job down.

Like the saying goes - "Less sound = more ground"
 
Any possibility of them coming out for the older bikes? My '04 could use some help at 94-96db.

That's good news.

The realist in me says "More Sound = Less Ground" - we're not going to get "more ground" unless we buy it.

Hasslbri and I had that same converstation on our way back from the Monticello Hare Scramble yesterday.

Sad to say but I think your right all we can hope to do is slow the taking of land use rights away.

The current mood of our lawmakers and executive branch is to either close or restrict as much ground as they can.
 
In a never ending quest for a quiet bike, I have done many things. I have done it to be less worn out at the end of the day, before the sound issue was even in the forefront as it is today. I have an FMF Turbine core on my '01 EC 300. The bike was tested at 88db at a local race, and I have tested it myself with myown meter at between 87 and 91db depending on surroundings. I have recently added a db snorkel which is a very interesting addition, though I have not measured it with the meter, it is quieter still.

At one point I modified a KDX silencer in search of the 82db my brother in law's KDX blew at a race, but It blew 86-89 db. (I think the variances are from being too close to other stuff.) I even painted it silver because one of my friends commented that it was an abomination to have that silencer on my Gas Gas.

If anyone wants it, it'll fit the early Gas Gas.
 
I installed a Stealth on my '08 EC300 a few weeks ago. I perform sound checks for our local club at events, have all the equipment and am well versed in the J1287 Sound test standard. My 300 blew an 85.7 at my house which is about 2000' altitude. We checked it at our last event 2 weeks back at about 5500' and it blew 83.5. I am very happy with the results and well worth the money in my opinion.
 
Wow, that is impressive. My Husaberg with the Ti akrapovic (which happens to be bigger than the muffler on my turbo diesel p/u) whispers 90 db which is the quietest I've heard. The sound testers always marvel at it's stealthiness, and this new Q will put mine to shame. Good stuff!
 
I'm anxious to see how mine will do. It didn't sound quiet in the garage on the lift with a bunch of tools rattling themselves off the metal deck :D , but even in there I could hear it definitely took the edge off.

IIRC my TCII blew 92dB the last time it was actually measured last fall.

Steve,
A customer of ours installed one just before our last AMRA race and it
came through at an amazing 84db! He said there is no power loss either.
Great job from FMF!

Had my '05 MC250 sound tested this weekend.

Before - TCII with fresh packing = 92dB

After - Brand New Q Stealth = 83.6 dB :D

It was nice to meet you this weekend at the Theilman (Minnesota) Trailride and once again the FMF Q continues to impress me.

After two(2 hour) harescrambles and half a dozen rides (about 10 to 12 hours of ridng total) the "Q" blew 83 db (!!!) on the '07 EC200 I was riding.

I would concur with other statements here that the "Q" has negligable, if any, effects on performance.

Ironically I had to ask to be sound tested as the "sound testing crew" were ready to give me a "pass" without actually testing the bike as they where talking about how quite my bike was as I rode up to the test.
 
Nice talking with you too Steve. Would have spent more time but was anxious to get out and abuse my body a bit more. Those guys do a great job on those trails.

I also forgot to report that my butt dyno detected no affect on performance with the Q Stealth.
 
I'm amazed how quiet this thing is. Now it sounds like my engine is falling apart. :o

No question, the quietest pipe I've ever had. Fit is just a tad funky though. It raised the pipe up a bit which put a lot of pressure on the rear hanger on the header pipe. I don't think it will hurt anything though.

I couldn't really tell a difference in power but I rarely wring it completely out. The neighbors definitely aren't going to hear me sneaking around in the woods behind our houses.
 
Yeah but, that would raise the price.
Then everyone would complain that the Gas Gas' cost too much.:(
