It is federal law to have a cat on the car. Manufactures are required by law to warranty the cat for at least two years.
Recommend just pulling on a high flow cat.
Chances of getting caught? Low unless your car is towed, impounded, e.t.c. Nothing worse than getting huge fines just so you can stick a finger to the man with an unstoppable 3 horsepower increase.
