Anyone have an aftermarket catted downpipe installed and tried to pass smog with it? I'm considering buying one, but I don't wanna have to do the stock-parts-dance when I have to get my car smogged next time.

Will it pass with the aftermarket cat?

Not an expert, but I don't think it would pass visual inspection.

Here in california, visual is required.
They might ask you about it, but they most likely know.

Whether the emissions aspect passes, depends on the cats and tune im assuming.

Next time is 3 years or more from now, 6 years for new cars in Cali.....
So, that may help with decision.

Thanks for for this!!! I had to look this up to clearly understand the rules. I also had no idea but still bought my downpipe anyways.

"Vehicles registered in areas subject to the biennial smog certification program are required to submit evidence of a smog certification every other renewal period. Owners of vehicles six or less model years old will pay an annual smog abatement fee for the first six registration years instead of being required to provide a biennial smog certification. The registration renewal notice mailed to you by the department will indicate if a smog certification is required. If a smog certification is required and you have not had a smog inspection, you may still pay your registration fees to avoid any late fees. However, you will not receive your new registration or year sticker until the smog information has been received by DMV........"
