Do California 986's have extra smog equipment?

[Davev]

Slate- my question was more about horsepower robbing smog parts. We don't do emissions around here. Some cars have special models for the CA market that are different for all other states. I would avoid those.

So now the issue is- since the 986 is built to meet even the worst (most stringent) state emissions standards- there must be some modifications some of us can do to remove those extra items. But thats a subject for another day.

For the most part, very few exceptions, cars are being made to be 50 state legal, not worth it to the manufacturing process to differentiate. Maybe that would clear things up for ya. Buy it and drive it, the gov as screwed up everything across the nation.

To my knowledge the one big thing that is different in the U.S. cars versus ROW cars is that we have four catalytic converters while the ROW have two cats. The extra cats can be eliminated with a straight pipe and generally is worth a few hp. Downside to wliminating the cats is it won't pass the visual inspection part of as smog check and it may not pass the sniff test if one is done.

Well, don't get too excited about all that hidden horsepower that you will unleash and transform the car. Many have tried with pretty limited results. The only real "unleashing" I have seen is the 3.6L transplant.

I did the 2nd Cat deletes, There are 4. 2 in the headers and another 2 downstream that have no Sensors in them.

The 2 downstream sensorless 2ndary cats can be easily removed and still pass CA smog standards.

The 2nd Cat delete frees up some restriction along with my aftermarket Top Speed mufflers and improves the exhaust note and improves the throttle responsiveness on my 2001 "S".

2nd cat deletes tubes are an easy job ~$200 also from Top Speed.

I love the exhaust note and throttle response now.

Search "2nd cat delete" on the DIY page and you will see lots of info on this with pictures etc.
