Yes the q core does restrict the air flow some resulting in less power but not alot, you can remove install in @ 1min so see for yourself. My wife does not like to ride it w/o the core so i leave it out. I agree
Big V the gain is on the bottom end. Pick up the NKG idirium plug its helps,
better than the stock plug.

There is a difference in the level seems like what I read somewere @10 db's more w/o the q core, as far as rideing around the neighberhood Its
a good idea to have in but on the trail most of those folk are like minded
and wont mind. I do bring mine along just incase someone does have a issue, if I like'em i'll put it in.
