Message Having decided on the SpecZ system, I now have to select between the H or Y pipe configurations. General dicussions I've read state that Y pipes flow better but are louder. In the case of SpecZ this is partly because they use smaller resonators.

Is the marginal increase in performance of Y over H noticiable? How about the increased level of sound?
