Passing Smog
I can pull my results from the last test if it will help.
A while ago my car wouldn't pass the smog test, I am going to give it another go. Since then I have replaced the plugs/wires, installed hooker 2055's, a new 3 inch. magnaflow cat, and 3 inch catback.
Will the replacement of the plugs/wires/cat make enough of a difference to pass? Based on any experiences from you guys.

that CAT has to be CA emissions compliant, otherwise it won't lower your emissions enough to pass.. also, you may want to read up on how to adjust your timing temporarily to get it passed the sniffer test... also since you installed the headers, you may want to install a heated O2 sensor, that's if you don't already have one...
