catalytic converter for 96-00 EX?
hey guys, anyone here in cali use an aftermarket, SMOG legal cat? i just started throwing a p0420 (catalyst system efficiency below threshold) so i'm pretty sure a new cat is to be ordered. i checked out my lhd(local honda dealership) and they quoted me something near 1100bucks!! i need something soon so i can erase this damn cel! thanks in advance.

isn't the o2 sim a ghetto version of fixing the problem?? 
i'm not entirely sure what the o2 sim does...help?
also, since civictildeath had a problem with his o2 sensor when he threw the same code, do you think that that could be the same problem with mine? i'm about 90% sure the o2's have never been changed(the car is at 120k). i figured that it was the cat though(high flow cat from landspeed racing) cuz when i went to go get smogged in one of the categories i was something like 3000ppm over the limit (gross-polluter). should i try replacing the o2's first and see if that clears the code?

Re: (Yoshiod9)
The secondary O2 sensor is whats responsible for letting the ECU know that the catalytic converter is healthy. O2 sensors also have a service life of about 75-90k miles. With yours being at 120k, thats more than likely the problem.
