Averaged in the high 20s, with 32 on the highway last week. I just finished having the 3" Magnaflow installed, and now I can't keep my foot out of it. What is it about that sound? I assume I will calm down after a few days.

Nope, and add a Solo High Flow CAT for an even better sound

Nope ... over 12 months with mine and I am now around 17-19 MPG in the city, where I use to get ~24. Thank God for the HWY trips, because I get 34 MPG on AVG on longer trips. I gave up on worrying about MPG, because if I was worried I would buy a hybrid ... the GXP is a sports car, so that is how I drive it.
