A while back I was working regularly at a suburban house in a normal middle class area. Work involved leaving or arriving at either 7am or 11pm. At the time I had standard pipes that'd had the first two baffle slightly enlarged - still within legal noise limits though. We had "anonymous" complaints from a neighbour about bike noise, though when the manager door-knocked about it no-one would own up to it. Pity I'm not still working there now I have the Thunderpipes on.
