Are you sure it's stock except for exhaust?

Well, not sure right away what would cause the really bad gas mileage other than do you drive the crap out of it? Rev it high, etc.?

Get a chip/tune and that can make your gas mileage better probably...

Dude, somethings wrong. Something like that should throw a code I would think. My 04 gets about 22 mpg and has the same mileage. Somethings screwed. Did you buy it with a couple dead bodies in the trunk and not know it... that extra weight could cause some loss too.

In comparison, I get about 12 mpg in the city when I'm driving aggressively, but when you look at what's done to my motor, you wouldn't be surprised....

I get about 17 mpg on the highway.
