LOUD PIPES DO SAVE LIVES!!!!!!!
Not really, just wanted to scream that. I bought a used Harley with V&H short shots on it. They were maybe 30" long with no baffles and OBNOXIOUSLY LOUD.
Thing is, the bike ran terribly with no appreciable back pressure. I honestly don't know why you would do that to a perfectly fine motorcycle. I bought a set of stock headers with slipons for cheap on CL and the bike is so much more enjoyable now.
Now, for fairness' sake, some of the worst offenders are metric cruisers. So please don't blame Harleys for ALL of the noise.
