True. Same problem with my old Jeep. CEL would come on for no apparent reason. Disconnect the battery and reconnect, light stayed off. Happened 2 / 3 times.
About the muffler, you sure your not more interested in the exhaust tone than the mpg's? Know my foot becomes heavier after new exhaust. Like to listen to the sound for a few days until the newness of it wears off.

As far as mpg, in many cases, it's a matter of "New Muffler = Heavier Foot".
