Audi Catalytic Converter - MagnaFlow 5481943

Product Information

A catalytic converter is an emissions-control device in a vehicle’s exhaust system that reduces harmful gases produced during combustion. It uses a ceramic or metallic honeycomb coated with precious metals like platinum, palladium, and rhodium to trigger chemical reactions that convert Carbon monoxide, Hydrocarbons, and Nitrogen oxides to water vapor and oxygen.

• Check Engine Light: Often triggered by oxygen sensor readings that indicate inefficient emissions conversion.
• Reduced Engine Performance: A clogged converter restricts exhaust flow, causing loss of power, sluggish acceleration, or difficulty maintaining speed.
• Rattling Noise from Under the Car: The internal honeycomb can break apart, creating a metallic rattling sound, especially when starting the engine or accelerating.
