Watching this youtube video with Brock, he tests the gsxr 1000 stock exhaust header. He said that the crossover/balance pipes between cyl 1-2 and 2-3 will aid midrange but loose top end hp. Thats why the gsxr1000 stock header has set valves to cut off these balance pipes.
Has anyone tried blocking off balance pipes on their Hayabusa full system, like akrapovic, and tested the differece in HP?
