Anyone here know if it will pass Calif Emissions?
Modern Perf has one.

 

It should pass the sniffer but visually(if they notice) it will fail

 

Go catless most all lnfs in socal are

 

OK...so what about passing emissions? I take it they put the stocker back on?

 

Not worried about the visual inspection. I just don't see how it's gonna pass the sniffer though. I assume the OBD scanner on the smog test will show the cat is present?

 

Yeah put the stocker back on.

Isn't anything but a stock cat illegal anyways?

 

Yeah you must have the original cat on, not even an aftermarket one. I am catless, but keep my stock one in my trunk.

 

I have a modern performance catted dp and it throws a p0420 code.. where I live in Ohio if you have a check engine light you automatically fail emissions testing. Modern Performance did however give me a free Vibrant 02 senor defouler for free so idk if this helps.
