YES you should be able to pass smog test without a problem--both the test and the visual--Many people get stuck when buying a catback system because there is a lot of mis-information out there and myths.
Basically buy the system for the sound and the looks/quality----The HP gains are not what most people think--I would say 8-12 RWHP is about the average---A cold air intake and catback are the 2 most popular mods and both would gain about 15-20 RWHP----(Just my opinion)
