Good morning,

Con.

Federal violation of emission laws. You will not be able to have it emission certified with the check engine light on or the catalytic converters removed.

Pro. Minimal increase in performance. A lot more would have to be done to make it run better.

You can have performance and a catalytic converter at the same time with the right set up.
