It's true, people here really can't drive in the rain. What really cracks me up is how people think they are going to melt when it is raining out. When I am working (Costco) people will do anything not to get wet. They drive there cars all the way up under the awning (not worried there might be people walking there). It is soo funny.
I checked those out. The only thing that I didn't like is that it looks like they are mounted on 10" rims instead of 12". Douglas makes a 12" in a red lable.
I have yet to see anyone at Dumont run there side x side's this way. At first I was not convinced, but after talking to a lot of people from a rhino forum, this is the way to go. A great weight savings.
When you add a slip on you are increasing the air flow. When you do that you need to add more fuel. The best way to do that is to get a jet kit. Some exhaust slip on's like HMF will come with a main jet that will help with the fuel delivery.
