Personally, I love that sound. It means that you have high performance parts on your car and you're not messing around. For example, the very first thing everyone with a Ducati does is purchase the open clutch cover. Because they run a dry clutch system you can run clutch covers that are open to the elements. It rattles away and to the lay-man sounds like something is rattling inside the engine. To those who know, you just see a little grin form on their face and the look of "yea...That sounds AWESOME!!!"
