Question Muffler's effect on RPMs?

I added the flowmaster 40 series last week, and I will start off my saying that I love the sound. One thing I noticed on my way to work this morning is that I was was running close to 2000 RPM's at 60 where I used to only run 1800. Is this the effect of my dissapation of back pressure?

What can I expect from gas milage?

Any other effects I might notice?
