I got a 09 UC with a set of Rush pipes 1.50 and a large volume air breather. Took it to the dealer and had a map down loaded. It has a pep in it but run hot in the exhaust area. My pipes are starting to discolor and my leg real hot from the back jug pipe.. thinking it might be to lean. The gas mileage is high thirty right now I have about 3200 mile on her right now .. any info would to hear thanks..
