west central illinois
We have run both cats and cummins and from my experience I would take a red top N14 over anything else. Ours was 525hp and would pull better than the 550 cats and got 1.5 mpg better fuel mileage. The 3406E would be my second choice but I had some issues with one truck that soured me on cat.
