Random technology high flow cat is what I use. With out a cat your car will not pass smog test and the rear heated O2 sensor will see to much oxygen and turn on the check engine light code P0420 for cat converter under efficiency. It is illegal to modify or remove emission controls.

Cat-back is referring from the cat and behind. I would say a'straight pipe' or get one from randomtechnology.com
