I only rated this a 4 stars because it melted my stock exhaust air filter cover. Will try exhaust wrapping and heat shields, to cut down on the heat. Its nice looking and sounds nice. I like it because , its a shorter exhaust and doesn't block the look of the rear tire. Its definitely loud, only because the exhaust dumps out where you sit at. So I definitely recommend ear plugs when riding. Outside of that. Its all good.
