Anyone know a good silencer to use with the Honda Power Kit on the 06 450R electric start?
The Kit replaces the pipe but just replaces the silencer core on the stock Honda silencer.
I want to know if anyone has any experience with an aftermarket silencer for this setup.

Will I gain any Hp by using an aftermarket silencer? I plan to add a K&N to try to get a bit better airflow. If I do that and add a silencer, what jetting will I need?

Thanks for your help.
