Hi-Flow Cat in California

[Defiant]

Is anyone using a high-flow cataclysmic diverter out here?

Did you pass a smog check with it on?

ya if by some means you can pass emissions in this wonderful state then they will try and find some way of screwing you over in the visual inspection part of it. Either that or the cops will. oh ya #### emissions get a test pipe.

yes

I passed with a 2.5" hi flo cat. There's more to passing smog than just having a cat; the car must be tuned "right".

i passed smog with my gutted cat, just turn the boost down...maybe lean out ur few a smidge if ur worried......put it up at idle so it actually idles

thats all you can do really

there is also a gas and oil additive that you can use to pass emissions.

A highflow cat will not make you fail emissions. A poorly running car will. As said before, it is all in the tuning. Look at my mods, I was able to pass, it just took me some time to get the car lean enough to pass.

The previous owner of my car ran it without the cat and it passed emissions fine.

My car won't pass smog, the hydrocarbons at idle are too high.
I have a 2.5" high-flow cat and the smog guy told me that was
probably the problem. I guess I hafta put my stock exhaust
back on.
