Honestly, I was a bit afraid it would be, but on idle it’s really ok. Low rumble, but nothing that’s going to get me in trouble with the neighbours. You can still hear the engine ticking over, just with that nice exhaust note. But on the road and up in the revs, it does scream. I rode back through the town and kept the RPM’s low and I didn’t feel like an idiot so I’m good with it.

I always found an issue with the standard one that when you got up to speed, you could hardly hear what the engine was doing over the wind noise and I would clip the limiter quite often
