Maybe going to a straight cutout will cause a loss of backpressure and lose FE. But what about... a dual exhaust system, with the cutout allowing exhaust to flow to the 2nd muffler, which would be a higher flowing one. Has that been tried? Instead of going to lose all pressure, it just increases the flow... People say you can gain 1-2 MPG with a performance muffler, but they sound terrible. What if you could switch between the two?
