Does having a decat and uprated exhaust make you achieve a lower mpg figure?

I think my car is really underperforming at the moment. A few weeks ago I made the 207 mile trip down to dover with one or two stops for food on the way. I never let the speedo stray over 70mph as we were driving to Paris so all in all did not really want thrash the car! I put exactly 35 litres in prior to leaving as tank was on the red and it was empty by the time I reached Dover. To my best calculations thats well under 30MPG :S ??

Also even driving very cautiously through the gears and not really ever going over 3k revs I'm only getting around 19mpg.

Is my car seriously underporming or are the decat/exhaust majorly contributing to this?

Thanks Dan
