im not sure but most people remove 2 of the four and replace the other 2 with highflow cats it is not legal to remove the cats completely also you might actually loose performance cos you need some kind of backpressure

Throw codes and not get the increase performance that you are seeking. Highflow cats should be ok though.... Search for cats, I've asked the question before.
There are devices called O2 simulators, but IMO you would be best off getting high flow cats and headers.(NO SHORT TUBE HEADERS)
