sorry, little late
but we stock these Magnaflows. They come in 12" and 18" body
lengths. Both flow the same, better then stock, but the longer one
is just a little quietor then the shorter one. Mostly it changes the
cockpit sound levels. Youll hear both over stock, no doubt. Both will
easily fit in place of the factory huge muffler. I suggest keeping
the single set up to be honest.
