where could i buy a muffler or have one made, that has an inlet on one side, and on that same side has an outlet, and on the opposite side has an outlet? that way i can make a dual out let exhaust without differing much from a conventional single outlet exhaust. its kind of a whacky setup, but if i can find it, i can make my idea work. what i really want is a nice, low rumble, medium loudness exhaust, with true duals or dual outlet from the muffler.
