I did it and ran it for a while. Sounded really Cool at Idle. I really like it under hard acceleration. But at cruising speed which is about 3000 t0 3300 for me, the drone was just not what I was looking for. So I made some parts to Plug the holes but are still removable. I have to admit, the silence is pretty Nice. Even though I come from riding Harleys.
But I still wouldn't rag anyone for wanting the sportier sounding exhaust. I'm just going to ride silent for a while. I must be gettin OLD.
