This may sound awful but it's no real concern. Between bikes guns and head trauma I'm pretty far gone on highs and mids, really don't plan on living long enough to suffer.
As far as exhaust goes, what about a glass pack slip on? With maybe a turnout extension? The gz is not a big bike and will never mimic one but I think most people could enjoy a low rumble at idle to a high whine on the top end.
