Oh, one other thing.
I do not know where and when you will be running this kewel new buggy so I don't know the reg'z you will face but, out here in the west during the summer time a straight through muffler is not allowed on public lands (technically) because it has no spark arresting capability. One of the reasons I pulled the Race Bullets off and went with dual 'Super Turbo #17698' Dynomax. If the rig is loud; I have seen rigs shut down on the spot for this, from dirt bikes to 4x4's. Sure it is a easy regulation to hang people out to dry on. Chicken Poo-poo maybe however living in the wildfire zone I can live with it, if it keeps my house from being burned down.
