A clogged catalytic converter restricts exhaust flow and raises emissions. Signs include:

Sluggish acceleration o r power loss

Excessive heat under the car floor feels hot

in fuel efficiency

Sulfur o r rotten egg smell from the exhaust

Check engine light with codes like P0420

How to confirm: A backpressure test o r thermal imaging of the converter before and after operation can help diagnose this.

Fix: Catalytic converters are costly to replace approx. $150–$600, but essential for legal emissions compliance.
