I just installed new Reinhart true duals on my 05 Ulta. Took it for a ride around the block 2mi. Rechecked all bolts and noticed that the pipes next to the cylinders are blue? The heat shield is not affected though. Is this normal??
YES & NO. Highly likely that you are running too lean, creating too much cylinder heat. Definately retune your fuel / air mixture following a change in the exhaust system. With that said, the inner (primary) pipe will surely blue over time, especially during hot weather / slow riding conditions.
