Silencieux aftermarket

Suite a la nouvella loi de test des silencieux avec le sonometre je pense bien que plusieurs se demandent si leur silencieux est conforme ou pas, je ne parle pas bien sur des straight pipes et je ne suis pas sur des 50/50, a moins pas tous, je parle du monde qui ont changé des silencieux pour l'estetique, pour le son ou autre mais qui ne sont pas bruyants.

Moi par example je l'ai changé par un Leo Vince, homologué en Europe, avec certiifcation et qui a un niveau sonore de 1dB moins que l'originale.
En Europe c'est facil, la Police vous arrete et vous devez leur montrer la certification d'homologation et voilà ..

Ici on ne sait pas encore, bien sur moi j'ai le niveau sonore par Leo Vince de 89dB mais c'est une facon de mesurer differente.

Parce que faut penser que meme avec des silencieux d'origine on peut depasser la limite permise

j'ai donc ecrit a Leo Vince pour demander leur opinion.

Voici la reponse de Timothy F Calhoun, vice president Leo Vince, si quelqu'un veut traduire pour ceux qui ne lisent pas l'anglais.

Hello Massimiliano,
Although we do not sell directly to Quebec currently I am quite sure some of our product has filtered into that market. We have been strong proponents of J2825 since it inception and were one of the companies that participated in the development of this sound standard which was developed by the Motorcycle Industry Council as a means to reliably conduct roadside sound tests. While sound remains a hot issue in most communities we have also recognized that often times this is not due to the majority of responsible riders and owners but often just a few exceptional offenders that are creating the core of animosity towards the motorcycling community.

This test should allow for these "worst" offenders to be quickly identified. J2825 allows municipalities a quick way of reliably testing roadside to see if motorcycles remain in an acceptable sound range. Better yet for riders it also allows riders the ability to know what these ranges are and to be able to quickly resolve the issue should one arise, or to defend themselves should they be ticketed without testing for noise.

With that said we have tested our different LeoVince exhaust designs and to date have found that our exhausts installed correctly with our dB killer insert easily have met and passed the J2825 sound test.
There currently is not a stamp or official way to designate this on exhausts but we are also in the process of creating EPA approved exhausts that will meet an even lower sound standard for the upcoming California SB435 law.

In my opinion, the European and new SB435 sound laws are a considerably more stringent test to pass than the new J2825 regulation.
I hope this sufficiently answers your question.

You are free to post my message and I am hopeful this may help dispel fears around this new regulation as I think that in the long term it will help all of us to continue to enjoy what we all love so much, riding!

Best Regards
