High flow cats and CA emmisions

The Deuce · 08-22-2002, 01:10 AM

I was wondering if anyone can give me some information about modifying the cats in California. I hate having 6 cats, and am cuirous if I could run an O/R H-pipe in front of two high flow cats and be ok, or even run an catted H or X and pass.

I know the laws are strict, but I haven't smogged a car in about 5 years. Please let me know.

I'd try just running a two cat h pipe. I'm sure it would pass. Plus you could still make good power.

My concern is we have a pretty strict visual inspection. I know a catted h would pass the sniffer, just don't know how half these guys get past the visual.
