I put Cobra powerport head pipes on mine with stock mufflers. They scavenge good and have a full size crossover. Interestingly the front cylinder goes mainly out the left muffler now and the rear cylinder goes more out the right muffler but is also getting scavenged some to the left. The H pipe style connection between the pipes aids low end to midrange. Its a good design.
Not too loud with stock mufflers. Will try cvo mufflers later. 2016 RK twin cam HO 103
