    Has anyone figured out how to get better gas mileage for the cadillac Ext? I'm not concerned with more horsepower.

    I put a K&N Cold Air Intake System and noticed an improvement in gas mileage on my 07 EXT.  But then I put a cat-back magnaflow dual exhaust system and loss more gas mileage than I originally gained when I installed the Cold air intake system.  I think it might have something to do with replacing the massive exhaust pipe with the standard size pipe that leads into the magnaflow muffler.
