Catalytic Converters for CA '91 ZR-1
Can't seem to find these. They are part of the exhaust manifold. Any suggestions?
Car is failing for NOx emissions in CA. Tried all the tricks - been getting it through for the last 4 plus years with the Marc Haibeck suggestions but not this year. The only thing left to do is the converters. |

Are they different on CA cars? I took mine off at around 30K miles and have them boxed.

Re: Catalytic Converters for CA '91 ZR-1
What were the readings on the smog? I'm in Ca,mine failed twice because of an over paranoid smog tech. I've got a few suggestions,send me a PM if you like,there are options if you absolutely can't find the cat.

Re: Catalytic Converters for CA '91 ZR-1
The State has some help when it comes to failed smog tests and defective cats that are no longer available. I've seen where one owner got a deferral from the State where he no longer had to test the car. And something to keep in mind installing used cats on a car is illegal,that right there helps owners as far as proving the cars are no longer available. The State can't legally out law a car that was built to Federal emissions standards at the time of manufacture. The State of California has lowered the max Nox levers over the years. When I bought my car back in 2007 the max Nox level was 702,the State has lowered the max Nox level to 502.
