Thanks for this,
Yup the one I have now is too loud / boomy / drones at speed - I just recorded it at start up and its 113DB. It sets car alarms off if I rev it in a multi storey. I don't want that.
Stock, on the other hand, is too quiet / dull, agreed. So I am looking for something with a decent growl, louder at idle but not obnoxious, and no annoying drone. Decided it will definitely be the Dansk, so now just too choose between a Sport Sound or Super Sound...
