I need a cat so I can pass CA smogg. But I want the best one for the turbo, I have flying miata turbo exhaust and wanted to know what is the best matched cat?

I would also like to do a down pipe in the future, just trying to plan ahead.

 

I guess any 2.5in high flow cat designed for the miata would work.

 

damn andy is everywhere today

 

In Illinois, they hook the computer up to the OBD, and then put it on a sniffer at idle. I've passed with a test pipe.

 

Yes, maybe in Illinois but this is California were talking about here. There savages!

 

Well what is your emissions procedure?

For us, they drive on a half mile track before, pull the car into the bay, type in the VIN to get past history, put a sniffer at idle, OBD/OBDII computer hookup, analyze, and away you go with either a pass/fail/void.

 

I think I will just go with the cheapest stock one I can find. I can use the straight pipe when I dont need the test! Moss sells a stocker for like $120

 

turbotony has one that he sells for 115 shipped. i have it and it is very nice. 2.5" high flow. he also has a 2.5" downpipe that he sells that i also have. very nice stuff from him and super fast shipping. just a happy customer

 

In CA, for a <96 car, they enter your VIN, sniff the tailpipe at idle, then put you on a rolling road and sniff the tailpipe under load at 15mph and 25 mph. They also check the timing, and perform a visual inspection to ensure that all emissions-related hardware is present.
