Is it an off road x pipe? If so, thats the culprit. Have you actually calculated your mpg or are you just assuming it's terrible?

my mpg is 14-15mpg city and if the off road pipe is the culprit i might take it off thanks

14-15 would be low if you babied the car around the city. If you get into the throttle a lot, as most of us do, thats a tad low but still on par. Do you have an exhaust leak by any chance? The o/r pipes do produce some stank, but you shouldn't be smelling it in the cabin unless you have a leak.
