May 9, 200917 yr comment_343286 hi guys. i have a Toyota Corolla SECA CS-X 1990 with the 4A-F carbed engine. Just recently i found video of this cars exhaust. The guy that installed the performance exhaust on the SECA claims that: "The engine wasn't designed to have a cat in the exhaust system, so it gains about 15 horsepower(I am not making that shit up). The power gain after removing it was ridiculous." I'm wondering if this is true before i do any exhaust upgrades. Is it illegal in QLD to not have a catalytic converter?
