Louder doesn't always mean more power however, if you want more power over your stock muffler you will have to gain a few db's.

I recommend HMF. Those guys treated me good. My Penland race system is LOUD but when I add the quiet core its isn't that bad...just a little bit more noise over stock.

i am looking for a slip-on for an 05 vinson that will give me the a considerable gain in power. i don't want it too loud so that the neighbors don't complain when i'm plowing in the winter. i looked at the eco-system, but heard it does not add know where near the power the utility series does. everything i read about the utility series says its too loud even with the quiet core. any suggestions would be greatly appreciated to regain the power lost from the mudlites. thanks.
