It should take three engine cycles to through the CEL anywhere from 150 to 200 miles

Why did you do that? You thought you were going to gain power with no exhaust? :confused:

It took my car about 12 hours for the CEL to come on after removing the cats.

less backpressure = more power.

he should be getting more power with no exhaust.

get yourself an electrically powered dump valve, for racing, and run it through the exhaust for normal driving.
