I may get "burned" on this post, but here goes. Few nights ago, took a buddy for a quick 45 MPH run down the dirt road. Once, home I noticed the exhaust pipe between the engine and muffler glowing red hot! I've owned all kinds of wheelers, but this alarms me. Talking to a Polaris Ranger friend of mine, says he has seen the same thing on occasion. My run was not "on the floor" but for a total distance of about a mile. Anyone have this experience on their Viking?
