Benefits of a Properly Functioning Catalytic Converter:
Reduces Emissions: Helps meet environmental standards by minimizing pollutants.
Improves Performance: Enhances engine efficiency and fuel economy.
Prevents Damage: Protects other exhaust components from excessive heat and pressure.
Legal Compliance: Ensures your vehicle passes emissions inspections required by Pennsylvania law.
