Rep Power: 0 New aftermarket catalytic converter or used OEM?
Hi guys,
I have a 2004 Civic. My catalytic converter needs to be changed. It can't be repaired.
I have two options:
1) buy a new aftermarket part
2) buy an used OEM part
Which option is better? Buying a new OEM converter is out of the question. I don't have $600+ to spend.

You can find a CARB certified cat brand new for around $350-400. The cheaper cats haven't been known to last. I guess it depends on how much a used factory cat is and how many miles are on it vs a new CARB one.

Does it have to be CARB certified? I'm in Montreal, Canada so I don't need to pass emissions.
What do you think of this one on Amazon?

If the shipping to Canada is not ridiculous I might buy it.

Advance auto parts has a online code for 30% off using trt30 at checkout I am going to have to buy for my 6th gen due to cracking comes down to 179 and it's lifetime replacement so I don't care how long it lasts

Re: New aftermarket catalytic converter or used OEM?
If I'm doing it for a customer, they don't even get the cheapo option, they just don't last reliably. Half the time the cheapies won't even make it past the 1 year warranty period before the P0420 code comes back.
New OEM, or California CARB approved are the only choices I will offer a customer.
If they want cheap they can go be pissed at someone else.

Thanks for your advice ezone. I will go for the other Dorman that is CARB compliant. It's only $40 more I think.
Just curious, what would happen if you decided not to change the bad exhaust manifold/catalytic converter? Mine is so badly cracked that none of the mechanics wanted to even try welding it.

I can predict the future: It will not heal itself.
Leaking exhaust =
Carbon Dioxide,
Carbon Monoxide,
Stink,
Noise,
Pollution,
Inaccurate fuel injection calculations due to air leakage
Maybe more but I'm about to fall ZZZZzzzzzzzzzzzzzzzz.....

its like having a monumental diarrhea but your exhaust port suddenly gets 10% of its original size...

I tried a cheaper option first before replacing the part. I brought the car to a garage and they welded it. 1 kilometer later my car just died at the red light. Had it towed to a garage and the mechanic believes it's a bad knock sensor so he will order the part and fix it tomorrow.

Do you guys believe it could be a bad knock sensor? That's what the mechanic's scan tool showed but I have a hard time believing it's only that.

Now I talked to my trusted mechanic and he believes it's the Crankshaft Position Sensor.
If that doesn't work I'll try to test the catalytic converter.
But I'm confident that the problem is the Crankshaft Position Sensor. Another mechanic told me the same thing.

you have a code scanner? you should have a CEL with a code for a bad sensor. i would start fixing what you know is wrong with the car and go from there.

I received one by mail today.
But the thing is no CEL is on.
The mechanic will change the Camshaft Position Sensor today and if that doesn't work he will change the Crankshaft Position Sensor too.
After that if it still doesn't work I will bring it to another mechanic who specializes in electrical problems.
