Finally purchased Dynomax coated headers---Need help on making some final decisions. First, I am trying to decide as to whether to use an X or H pipe for a true dual exhaust. Additionally, what type of Mufflers to use-and whether or not to use cats. I want it quiet. Has anyone used dual Borlas on a 350 Elky--(1985)???
