FMF Q Help---got hosed on Ebay

[bparsel1]

Hey Everyone,

I've just spent the past hr searching threads and I can't put together the info I need. I know this has been beat to death but I need help.

I recently purchased a "Q2" for my 400 off ebay, well I got it and it's a regular "Q" ---I got a great price and it's brand new so I don't want to re-sell it. But the bike seems way loud and I'll get nailed here in Michigan if I'm over 94db's.

Is there any new solution to quiet down the Q muffler? Insert, new packing material, anything? It sucks to buy a new pipe and then realize you'll only be able to ride with it 1/2 the time:banghead:

Anybody know what DB's the Q will blow on a 400?

Thanks!

You should probably call FMF to see if this quiet insert would fit your application.

Yeah, I hate that, in Michigan it's at half throttle, I assume it's that way everywhere?

Ken--I saw that insert this morning on their website. I'll def. give them a call I've just been waiting to see if someone might have already found a solution.

Thanks guys, hopefully someone may have an idea.

The standard is different for every bike but Michigan should be using the same standard as everywhere else.

I had the first generation "Q" on my 04', you can get a packing pillow right from FMF specifically designed for the can and it comes with easy to follow instructions... I think when I bought it a 2 or 3 years ago it was $16...

Here it is in the TT store - "Q" Pillow P/N, 27-1968, $25

This should get you down pretty close to 94db, I used to pass sound checks with it at the races where the limit was 96db and that was with a tach and probably 1/3 throttle...

the folks @ FMF are very helpful

I have a 00 WR400 with a Q. It had got loud with the original packing. I repacked it with Silent Sport (I think they were bought by FMF) packing. it is a stringy kind of packing vs. the 2 stroke fiberglass blanket looking stuff I have used in the past. I went from over the limit to around 93db at the last sound check.

Kirk and Don Thanks! That was the info. I was hoping to find.

It sounds like changing the packing should get better results. I would hate to have to put my stock exhaust back on for every Enduro race or park I ride at.

Try repacking with Silent Sport or MSR HP Silent Sport packing. MSR just repackages it with there own name so it's the same stuff. You will need at least the 450 gram bag.

I have the FMF Q on one of my WR400s and the Q2 on the other. IMO, with both pipes freshly packed, the Q2 is the louder of the two pipes - has a real bark to it, but it also produces more power.

Really? That makes me feel better about the situation then.
