Common Issues Addressed

• Check engine light caused by catalytic converter efficiency faults
• Exhaust leaks at the converter connection points
• Failed emissions inspection on the listed Honda Accord applications
• Corrosion-related deterioration of the original converter housing
• Fitment problems from non-direct replacement exhaust parts
