3dB is half the sound pressure, so while it's only '3', it's actually a substantial reduction because dB is a logarithmic scale.

The Diameter of the exhaust Hole effects the "loudness".......if you choke the exhaust hole down to around 1", it will get Much more quiet......that's what the Quiet Core part does.

I put a spark arrestor in

Put the powers in and spread them. Gets it out without harming the edge of the arrestor.

You didn't say what the sound level at idle was after the arrestor was installed

I got a fmf and i got a wr as well. The Fmf is way! to loud. Its louder than my mx bike. Even on track you can get into trouble with fmf. For trail riding its way! to loud. Locals will freak out..useless for me. Will sell it.

The spark arrestor quiets it down a lot
