After the catalytic converter is destroyed, a Flowmaster Delta 50 replaces it.

Not legal in many states, thankfully. Sometimes you can reset the check engine light and it will stay off long enough to pass your smog test, but it's a good idea to have the codes read to see what's going on under there.

Okay you tell that to the smog technician, forest ranger, beach patrol and city services personnel in charge of refuse, burning and toxic waste disposal. I'm sure they'll all just let you off. 
The CEL light should always be addressed regardless if you are in a smog state or not. It could be related to nothing of significance (Ioose gas cap, etc.) or it could be the precursor to your car blowing up.

In california its really tough to pass a smog test I had a oxygen sensor replaced and the check engine light came back on, Complained to the shop that did the work and they had no idea why the light returned finally found the answer on this site http://repairpal.com/check-engine-light "On vehicles 1996 and newer, using an inexpensive "universal" oxygen sensor will cause problems with the emissions system." How frustrating is that these shops are using universal oxygen sensors and charging dealer prices for the part, They finally put the dealer part in and the light went off and passed smog only took three weeks and I had to show them this website before they would put in the correct part.

We love it when people are trading in cars with a CEL on. They will ALWAYS say..." It's probably a loose wire or something minor"
Yeah, right!
A store HAS to assume the worst because that's usually what it is. It can be a bad transmission, bad computer or a bad converter.
We will appraise the car accordingly and so will any smart store.
Had a trade in last summer with an air bag light on. A Volvo naturally. The Volvo Dealer charged us 1200.00 to fix whatever it was. It wa NOT a loose wire!

#1632 of 1688 check engine light concern by jeffreyb4
Apr 08, 2009 (11:51 pm)
My check engine light was on, code checked & cleared by a local mechanic. The code indicated PCM problem. The light came back on so I took it to a dealer to have PCM replaced (under warranty). The dealer checked & confirmed the PCM code and agreed to replace it at no cost. However, while at the shop, another code appeared that was not there before. This code indicated knock sensor and the dealer said this would cost $340. My question is, why did this code suddenly appear at the dealer? Is there a way to program this code to show up falsely? I think they may have done this on purpose and there was actually no problem with the knock sensor until they did something to make it show up. Is this possible? Thank you for any advice. Trying not to get the run around by an unscrupulous dealer.- kiawah (Apr 09, 2009 4:22 am)
