Again.. There are ways to pass. I live in CA, i've been through it all. I had my del sol track car smogged, registered with no cat, no egr, no evap, no bar sticker for the swap, tuned with full roll cage and no seat belts (only harness).You would have to pass BAR first. You can have the cleanest burning engine ever, but if it does not meet the regulations then its a no go.
