Seems like a variable choice question. Mine seems loudest on-the-throttle uphill two-up  -Mike |

To get a real answer to that question, you would need a sound meter and several candidates for aftermarket pipes, and fit all of them to the bike and drive by the sound meter for each set.
For "good enough" - you can assume Honda made them as loud as they could for your model year using the original pipes in their original configuration.

oem pipes are stamped to meet EPA noise requirements, so tend to remember that is 88db at one meter at 3k rpms.

Jiri,
When I was stationed in Germany 2006-2010 my Valk (OEM pipes) had to go through a yearly vehicle inspection. One of those were db testing, and I never had an issue passing.
Hope that helps.

Thanks Ice. Its 11y ago so I hope the limits weren't changed too much. I'm just surprised there isn't any official info from the mother Honda. Thanks. Ride safe. Jiri |

As I recall, when the Valk came out, it was touted as one of the quietest big bikes in existence.
That's with no mods, piggie trims, truck stacks, holes drilled, Ragner cuts or glasspacs (though some of those can be pretty quiet).
And guys that extended the piggies longer than OE, got even quieter than stock.
One one of my bikes, the only thing not stock is flat cut 18" stacks (in replacement of the skinny metal stock pinched tips), with stock pigs, and they might be one or two more decibels louder than stock tips.

Here in the UK our bikes have to have an annual check to get our annual MOT certificate. Exhaust noise is down to the discretion of the examiner. No meter is used to check the noise limit. My standard Valk with 6 into 6 passes every year, the examiner I use says he has never failed a bike for loud pipes.
I could take it down the road to another shop and they may well fail it. All a bit hit and miss depending on where you take it...lol...
You won't have any trouble riding in Europe with loud pipes....they are getting hot on speeding though, that is where you need to be careful...

Thanks BigBob. You can be really surprised driving this days in Austria. They have a limit for max 95dBa and my friend bought last year brand new Multistrada (98dBa from new) and he had problem to entering the country and they wont let him drive on the roads with this limit!! World became crazy! Really. Thanks. Ride safe. Jiri |
