Does anyone know if High flowing cats are smogable for California Emissions? Also, is there any company that makes mids with Carb numbers on them? I want to make my exhaust system more high blowing but I just dont know if any are California smog legal.

As far as I understand it, relocating or removing fully operational CATS is illegal.

So no mid or LT setup can be used. Shorties and catted Y may be legal.

However, if I lived in CA there's only one route I'd go and that's FI. I think Procharger P1SC is carb certified (you'll need to check, as not living in CA I've never bothered to check).

And I think STS are trying to get their kit also certified.

With FI you just don't need all the bolt on's to make power. So stock or shortie headers work fine, as does the LS6 intake and ported TB.

You don't then need a lid, or pulleys and with the STS you don't even need a cat back.

So you could do:

ProCharger + cat back = 440+rwhp
Or
Stock + STS = more than 440rwhp

Well it's an option anyhow

Well, being from California myself I can attest to the LT's and re-location of the CATS being in violation of our SMOG laws. That's why I'm going with an ATI Procharger P1SC Kit and some shorties . Both are smog legal and I'm hoping to make AT LEAST 420 rwhp.
