Missing Cat Converter ?!?!?

I've owned my TJ for 6 months now and I just found out my Cat converter is missing....

The Jeep has been owned by 2 others (according to the title) so I assume one of them took it off. Thankfully I live in Tennessee where we do not have to do an exhaust inspection.

Besides being illegal I have heard a missing cat can affect performance in a negative manner while others have said it increases performace. As I have a 4 cyl so I don't want to "lose performance".

Does anyone have inputs of performance effects of not having a cat and which brand I should use when I get a new one?

There really aren't any negatives for engine performance by removing the cat. Increased horsepower by reducing back pressure and less strain on the engine caused by that back pressure is a good reason to not have it if you don't need to.

But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. James 3:17 (KJV)
