3dB is half the sound pressure, so while it's only '3', it's actually a substantial reduction because dB is a logarithmic scale.
Thanks
Hey man thanks for the video sick bike! Where did you find those pipe guards though? 😮
They are P3 carbon, I bought them at Rocky Mountain
@@sherburnoutdoors thank you !
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
I need help i took off mine but i dont know if it could happen something wrong or bad
What part number was the a tester? 040639?
Put the powers in and spread them. Gets it out without harming the edge of the arrestor.
Where do I find that part. What’s the brand
FMF, comes with the pipe
Do a video with that on a 2stroke
Unfortunately I only own a 4 stroke
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
You didn't say what the sound level at idle was after the arrestor was installed
Quiet bikes keep trails open.
