Have read the reasons for crossover pipes on dual exhaust engines. Many opinions and a few myths abound as well as the engineer speak one would expect as the definitive reasoning.
Just an observation on a R1150R header, which is a two piece,I had off yesterday and wondering if the 1200's have this reducer inserted ? I bet most thought it is a wide open channel on the 1150's. Just one of those engine-ered tweaks I thought about seeing this. I had seen this reducer before,but never gave it much thought as it must do what is was designed to do. It certainly restricts flow between the two exhausts.
