How Many Catalytic Converters? in 90 - 00 Lexus LS400 Posted February 28, 2020 Thanks. When adding two new catalytic converters, what else should I replace and what things should I watch for? Should I get a whole new cat-back exhaust system, O2 sensors (how many), things of that sort? Any help will be appreciated.
