15 mpg...whats the deal?

I have gone through 2 tanks of gas and my mpg has been between 15-16 mpg. The car runs great and the check engine light has not been on in quite some time. Yes, I cleaned my MAF sensor and reset the comp. I have not added any mods recently. I have noticed my Flowmaster mufflers are rusting out a little though. Do you think that my exhaust could cause the terrible gas mileage? It seems to me it could be part of the problem but to drop me down 6-8 mpg?!?!? Any help would be appreciated.

That's what I was going to say. Genrally when they fail you are supposed to go rich so you don't damage anything.

Dyno's are for pussies, I simply put chuck norris in front of my car, and proceed to floor it, he tells me how much HP and torque I have.
