Can I switch my Oldsmobile Cruiser to a dual exhaust system?
I own a 1992 Oldsmobile custom cruiser. It has a single exhaust with a single CAT. I want to install headers with a dual exhaust system. I want to know if dual Catalytic Converters are California smog check legal.
Answer:
Switching to a dual exhaust system from a single will be considered an emissions system "tamper" and will cause your Oldsmobile to fail the smog inspection.
