RM ATVMC delivers!
I ordered this part from FMF months ago, and was told it was backordered. Fair enough I finally called to see whats up, and they said I had to get it from a retailer? Good thing I called!

In any case, the part was perfect for the mini system on my kids CRF50. Without this insert the 4.1 was simply too loud.

Works as intended
Really tones down the bark, reminds me of the old KTM RFS EXC muffler tone. The bike lost some low end snort but it works better for offroad like that anyways. I had to slot the mounting hole to mount it.

Excellent product
Fit was dead on. Screw was proper size and the holes lined up. It works perfectly. Made the bike quieter and I think it sounds better. The previous owner had removed his insert so it was rather loud. Now it's deep and throaty. Great product.

Works as it should but pricey
It does what it's supposed to do - quiets exhausts and allows to ride in OHV areas where spark arrestors are required. I would prefer a circlip for snapping in the unit rather than a bolt. Unfortunately, my bolt vibrated out, and I lost my first spark arrestor. The bolt isn't ideal for quick install and removal given the limited access for installing the bolt.

Price is high for what it is ($35) as well, but it fits nicely when installed

Love FMF stuff
Nice pipe, looks great, sounds better than stock but not annoying! Also looks great, just a hair lighter than stock, installed very easy.

Sounds great, gives more power. Bought the quiet insert as well, as it makes it easier to hear other bikes when riding in groups.

spark arrestor.
They give you these now when ordering the pipe. I purchased this separate a while back. I never really used it, just carried it in my pack just in case I ever needed to use it. Slips right in

good product, bad install.
This quiet insert does exactly that, it reduces the bark of the exhaust to a reasonable level. My only complaint was with the install, wrestled with the screw for about an hour and ended up having to deburr the hole and use the old screw instead.

I have the Fmf power core on my raptor 700 what decibel will this bring it to approx?
A shopper on Jul 6, 2017
BEST ANSWER: I put an FMF Quiet Core in my Yamaha WR250F muffler. I don't know what decibel it brought it to but it took the high frequency bark out of it. The Quiet Core did not seem to have any effect on the power output. I hope this helps.
How long is this insert? Will it fit an 03 Honda Foreman?
Richard R on Sep 16, 2016
BEST ANSWER: This is for the FMF Powercore silencers only.
