Extreme
My sled was making a tingling noise (only when driving, never at idle) when I original bought it and about 200 miles later one of the y-pipes separated from the the flex pipe on the exhaust. Replaced the h-pipe, all 4 donut gaskets, and the clamps. Sled ran great, after about 30 miles of riding the tingling noise faintly started to come back and is almost as loud as before. I put the donuts on perfect and the clamps... I d'ont get what this noise could possibly be? any ideas?
