I still get 25-26mpg with no cats on highway. My wife can get 27 pretty consistently in my car but she has a lighter foot than me. I get 19-22 around town. My mileage did not change at all with the exhaust change. If I had known it wouldn't change I'd probably have left them on. Either the stock system flows very well or my butchered system isn't very efficient.
