Is that ecomodder-normal driving, or normal people driving? There is a bit of a difference
Part of the point of smaller exhaust is to get rid of the stuff before it cools off and starts to weigh a bit more and slow down from lost momentum. (Some sports cars insulate the exhaust system.....I wonder why....my Maxima in good tune gets close to 30 mpg while being a quick 4 door sedan and it has insulated exhaust.) Kinda like how a river speeds up at a narrow bend, a narrow exhaust pipe will let the gasses exit quickly and preserve the momentum they got from the engine shoving them out.
