I see the Leo Vince X3 comes with different inserts. My question is, has anyone tried out the quietest one? If so, how's it compare to stock? I'm debating whether to get a Q4, with the optional Powercore 4/Q4 insert(the small one, 1-1/8" I believe), or a Leo Vince. I'd like a can, just not a really loud one. I know the Q4 will work, but the LV sounds so good!
