I'm new in the forum and i hope it's good section. I would like to change my mufflers on my new bike roadking 2009 for us models stock. In europe, particulary france the mufflers are same in california. The song is bad. My question: It's possible to change for mufflers us and not modified ECM?

Thanks

You can do JUST the mufflers and squeak by but adding fuel to the mix would make it run much better. It looks as if you are asking to swap US mufflers on to your bike. That would also be OK with no modifications but here again, adding some fuel would be an improvement in the running of the bike. They run very lean from the factory.

Thank you very much for these precisions. On my past FXDWG I had race tuner forcewinder and mufflers SE. The legislation and the standards in Europe are harder, that is why I would have preferred don't touch ECM on my Road king stock but just change mufflers for better noise.
