2.25 or 2.5 will be fine with SI/SO

2.25 is good for duals.

Hmm

Maybe you can add 2ft of smaller pipe after the muffler to gain back a little backpressure . Shouldn't cost too much $. Just so we'll , know what kind of milage are you actually getting ? Divide gallons by miles . I checked mine yesterday and averaged 26.5 which included some 70 to 90 mph driving and about an hour of stop and go . E-fan and pulley really help!

It wasn't always that good

When I first got the truck , I could only get about 23.5 mpg ; and that was driving like an old man . To get that I had to keep the rpms in the 2300 range. With 4.10 gears , that means slow . E-fan added about 1.5 miles per gallon. The pulley after that added about another 1.5 mpg. And both mods add to the usable power. I do a lot of hwy driving, so I put on 32's to bring the gear ratio from 4.10 to about 370. Automatic transmissions use a lot of power just to force oil through the system [ some like fords c6 use over 60 hp] , so I drive a manual. I couldn't believe how much the damn clutch fan weighed. Do yourself a favor and ditch the damn clutch fan soon. As you already know . 3.0's don't have any power to waste. bob
