In y'all's opinion I understand that duals ( exhaust ) will help performance, but do you think it will save on fuel? On the 7.3...........

In my opinion, marginal. The engine is not large enough, nor flow enough air in near stock configuration to balance the cost from an economy sake. A larger single exhaust over stock is not as much money and will attain the same benefit.

Some guys like a dual exhaust and there is no fault in that. Myself, I only tend to use what works and go no further.
