What the Exhaust System Does
Your car’s exhaust system isn’t just about noise — it:
- Channels harmful gases (CO₂, NOx) away from the engine
- Reduces emissions through the catalytic converter
- Suppresses engine noise via the muffler & resonator
- Helps improve fuel efficiency and engine performance
When something’s wrong, it affects your safety, fuel economy, and emissions compliance.

Burning smell or exhaust fumes inside vehicle
