Bad Exhaust Smell! in Lexus IS250 / Lexus IS250C / Lexus IS350 / Lexus IS350C Club / Lexus IS-F / IS300h Posted April 16, 2018 I've changed gas brands and also replaced the catalytic converter and the smell is still very strong. The smell happens when I'm in stop-and-go traffic and than all of a sudden flog it. Anybody find solutions to this?
