Like Kelly said, one large diameter exhaust is better than duals. There is a reason you see most diesels with one instead of duals. But it also depends on what you want to accomplish. If you want the sound duals is the answer with a cross pipe some where. Get rid of the last "muffler" it is worthless. And remember, exhaltion process still requries inhalation.
