Get them done at the same time so she doesn't suspect anything. Then, at Christmas or your birthday (which ever is first), tell her that your car doesn't run right because the intake is too restrictive and wasn't matched to go with your exhaust. The intake may even make it fail emisssions...but it you put aftermarket intakes that are matched to your exhaust, the car will run perfect and pass emissions.
