Yes, a catalytic converter can influence the smell of exhaust fumes. If the converter is functioning properly, it helps reduce harmful emissions and can eliminate some of the rich, fuel-like odors. However, if the catalytic converter is failing or there's an issue with the engine, such as incomplete combustion or fuel mixture problems, it may lead to a richer smell in the exhaust fumes. In such cases, addressing the underlying issues can help mitigate the odor.
