Cali ref question (finally passed)

[IRUNEDM]

what cats did you buy

The cats are Walker CalCat Part #80301. The parts catalog has to show it's for the year make model of the engine. The Ref checked the part numbers to make sure of this. Also the dual in dual out cats that Mangaflow says fit my motor will not pass because it's not "Factory Configuration." Factory configuration is dual pipes off of headers into one pipe (O2 sensor) then y back into TWO separate cats. he didn't care what I had after the cats so I had it y back into my single exhaust to save money.

As for intake. anything forward of the maf didn't matter. I have a cone filter and because there are no vacuum hoses/sensors in the air box he didn't care.



This is a pic of the oem cats. my new ones are the same configuration.

Quoted for truth.

I too have a random muffler, and a cone air (without CARB EO number), and still passed visual inspection at the BAR.
