Is there a quieter muffler for my 430? Right now it has the Answer SA (non sparky) silencer and it seems like it's the right amount of noise considering the displacement and unit, but I would like it quieter. I feel guilty even starting it for a minute or two in the neighborhood..... The only "new" option I know of is the dynoports. Are their sparky or non sparky units quiet at all, when comparing it to the Answer I have now? Should I just have mine repacked and call it a day? I do not have the stock silencer available. I am using the stock pipe right now though, but might need to go get a new pipe since mine is bent slightly upwards against my tank as FYI. Just looking for a 5+db decrease if possible.
