Holes didn't line up
It was annoying that the holes did not line up for the 3mm screw. I have the TI powercore and this is the correct arrestor for that exhaust. I took a rotary file and bored out the hole on the arrestor.

Way Better on the ears!
The previous owner had removed the spark arrestor and at first I didn't mind the sound of the Powercore4. Over time the noise just got really annoying to me. This product basically removed the higher decibels and gave it a smoother lower throaty sound. Much more enjoyable to ride now!

Quite core spark arrester for FMF Power Core Four
The FMF quiet core spark arrester was the perfect tone reduction for the Power Core 4! No noticeable change in performance and I won’t be irritating the neighbors while riding. Very pleased with the purchase and highly recommend it.

Simmer down
This worked great on the Q4 which came on my used DRZ. It brought down the noise to a more tolerable level

FMF Titanium Powercore/PowerCore 4/Q4 Quiet Core Spark Arrestor
Excellent! It quieted my PowerCore 4 on my raptor 700r down to a much more manageable sound level. I don't really think it hurt performance much if any. I definately recommend it if you have a power core 4 muffler and don't want to draw too much attention to yourself...

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.

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.
Will this fit the FMF Powercore 4 I have on my Honda CRF100F?
Brayden T on Aug 19, 2018
BEST ANSWER: Yes, it should. I installed it in a Powercore 4 on my YZ250F and I do not believe the muffler openings were any different.
Will this fit the power core 2?
Dakota M on Aug 26, 2019
BEST ANSWER: No, this is designed to fit the Titanium Powercore, PowerCore 4 and Q4 silencers.
Can this fit the stainless steel powercore 4 for my 2017 kx250f??
Brevard M on Mar 28, 2019
BEST ANSWER: Yes it will fit the power core 4. I was very happy with the quieter sound it produces. Would recommend high temp silicone along with a small flat and lock washer to hold securely in place, small amount of vibration which may loosen the silicone seal.
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.
