Magnaflow Universal Catalytic Converter
Hi guys,
So the day I fear most has come (almost). My car is taking forever for the Catalyst Readiness monitor to set, and I need it for my upcoming CA smog test. Observing the oxygen sensor voltages, I can see the bank 2 cat is very unresponsive and slowly dying. Magnaflow has a universal catalytic convert that is CARB approved for this car. Since the second catalytic converter along the exhaust path (right before the muffler) is not monitored by the computer, since there are only two O2 sensors before and after the pre-cat that is integrated into the exhaust header. I was thinking about finding a shop that can cut that second cat out, weld the universal on in place, then make a hole for the oxygen sensor downstream of the univesrsal cat. Then both the pre-cat and the univesal cat are monitored, and hopefully that makes the computer happy enough to set the Catalyst monitor. What do you guys think? Or am I crazy? Spending $4000 just for emission purposes on a $8000 car just doesn't make sense to me. |
Why don't you just buy a used header/cat from Woody or ebay? Then it will still look stock for the California emissions police.

If the cat goes it is almost always the first one, the one monitored. Look up P0430.
Isn't there an obvious modification test to your smog test? Wouldn't a deviation side to side raise concerns? Will the ECU be able to compute the correct AFR with the imbalance? Lots of people have taken their exhausts off and they are just sitting around. Not to mention wrecking yards. |

He is a member of the forum. His user name is itsnotanova. He has the best used part prices on the internet. I almost can't believe you have never heard of him. He is famous on here :)

If you plan on keeping the car, contact Sunset Porsche for a new catalytic converter... Best price I found. You do not have to do both sides, just the converter that is failing.

Just get a used part to replace yours. |
So long as your car doesn't have any codes (CEL on or stored) and your emissions system is 'ready' for monitoring, you should pass CA's test. IIRC, CA no longer does a tailpipe test for cars newer than '98. Mine was in this situation and passed with flying colors. BTW: They did do a manual inspection of the system to see if the right equipment was still there.
It's a violation to install a used catalytic converter in CA. That's why it's hard to find a shop willing to do the work or to find one for sale in the junk yards. If you want to buy a new genuine Porsche one, ECS Tuning sells them on their website. I paid $1675 delivered a couple of months ago for Bank 2 exhaust / converter manifold. Bought it because I was sick of seeing the CEL come on. The other Bank is even cheaper. |

In CA 2000 & newer cars are tested via the OBD2 connector for system readiness codes. Same year warmup cats located as close to the exhaust ports as possible became mandatory. |
i too have to deal with Commiefornia smog police and they are really cracking down on these aftermarket converters. Be aware what you are buying if you go aftermarket as they look for the approved stamp on these. Went through this crap with a toyota recently that stated Carb approved but in reality there is a Calif only Carb approved too. Make sure it's the Ca and not the 49 state Carb. It is true the sniffer machine has gone away now being replaced by newer system that I believe plugs into OBD2 port. I would drive the car after clearing all codes till all the readiness codes are met. Also Calif allows 1 or 2 readiness codes to not be met depending on your year.
