I have the quiet core and it isnt very loud, it still is alot thoatier and louder than stock, without the quiet core it is VERY loud but sounds awesome.

without the quiet core its hella loud....my dad said it sounds like im riding right next to him, when im in my lil acre riding area lol.....with the quiet core though it helps a lot. It shouldn't bother your parents with the quiet core

Is the quite core removable from the HMF? In other words can you take in on or off as you like? Does using the quite core require jetting changes?
Thanks...

From what i hear you do not need to rejet from quietcore to without core!
How are the powergains?
And with the quietcore is it loud where people can be close to it without earplugs
