im making an exhaust for my motorcycle, should i do an h pipe or x pipe crossover?
its a cm400 inline twin and had this sort of h pipe/collector/muffler device stock (pic related) and it is known to greatly increase low to mid power and response from the scavenging effect vs true duals.
i just dont know if putting in the effort for an x pipe will have much if any gain over a simple h pipe.
