Thanks Moose, yeah it definitely takes the exhaust noise out of the equation. The only problem is the engine noise is what needs to be focused on. I've decided not to worry about it for now. I might even take the silencer off because I can really notice the loss of power now. If you are planning on a two part system of quieting the exhaust and the engine then I would recommend the silencer otherwise you will probably find yourself disappointed. Especially by the loss of power with no significant reward.
