The Q really did not quiet it down that much, it is a little quieter than the stock silencer.
Over all I really like the silencer but I usually put the stock one on when we go to the mx track. (which is not that often)
It mellowed out the mid range hit.
I usually drop one size on pilot jet and one on main jet.
I am going to try a gnarly pipe soon, I put a big dent in the stocker and want more low end and some of the mid range hit back.
