That is just plain anti-social and rather short-sighted Mr C.
I really dislike loud vehicles for many reasons, but mainly because of the adverse side effects that they are causing - running a vehicle that is loud enough to cause bystanders to take notice is what is driving bans & severe restrictions through out Europe at the moment.
The UK has been testing "noise cameras" & I understand that they are to be used here now - they already are in France. The Tirol in Austria has introduced a 95dB limit on one pass - lower than some currently road legal bikes can achieve with factory exhaust systems - with savage fines for those who flaunt the ban. Trentino in Italy introduced blanket 60 kph limits on many passes last Friday and - rather worryingly - 60 kph for motorcycles only on a couple of passes. Germany recently had 100,000 motorcyclists protesting across several cities about motorcycle specific bans on many roads in response to complaints from residents about noise. Some of these are 24-7 bans from 1st March to 31st October, so effectively a total ban rather than the "No motorcycles weekends & Bank Holidays" that have been in place on some roads for several years. Even MCN - who usually fit an aftermarket exhaust to each of their long-term test bikes - had a two page spead about noise a week or so ago.
These restrictions are being brought in to try to pacify locals fed up with a constant barrage of noise. By taking the "sod it" route you just help drive more restrictions.
Loud pipes don't save lives - they never have. They just piss affected people off to the point that they harrass their representatives into taking action against the problem. And lets face it, many of those representatives have well developed anti-bike chips on their shoulders already, so they don't need much pushing.
Do us all a favour & fit an effective mute, even if it means having to re-jet & loose a bit of performance - after all, you won't be able to use that performance anyway when your favourite road gets a restrictive speed limit or a noise camera after pressure from local residents.
