Default Exhaust MPG DECREASE

Hey guys,
Was running my exhaust open (no muffler) with a Poweraid Throttle-body spacer and was getting 360kms to a tank....put on a flowtec "red-hot" glasspack and now I am only getting 325-330kms a tank.
What gives?

Are you sure it's not mental? That is, you like the sound and are now a little heavier on the accelerator.

Temperature differences, PCM re-learn, slow down in exhaust velocity due to heat sync (muffler) and as previously mentioned change in mode of operation.

Default no muffler!

I am thinking of taking my muffler off and running with nothing. How did you like it when you took yours off...pros/cons.
Did you take it off yourself?
I can't seem to get the hanger rod with the nub on the end through the rubber hanger??
