Has anyone measured DB on the FMF Q without spark arrestor?

Pulled out my spark arrestor today, to test it..

I already have hotcams, and JD kit..

The difference was above my expectation..! The bike pulls alot stronger, especially in midrange.. Lifts front wheel in 4th gear on gravel at 50mph, sitting normal on the bike, no clutching :applause: (14-50 gearing)


Noise.. lots of noise :ride:

Anyone know the desibel level? It`s ALOT louder than with the spark arrestor...
