well, i hated the crossover also, it's a performance killer. this way, i get both pipes the same length, so i get the same back pressure on both cylinders. also, i'm deaf in the left ear, with both on the right side i can hear both cylinders, so i know if it's running right or not. this system is baffled, but they're very free flowing, so i get pretty good all around power out of them, combined with ev-13 cam, S&S E carb, Crane ignition and coil. other wise, it's stock, with a little over 100,000 on the clock
