Common Issues This Part Can Address

• Check engine light related to catalytic converter efficiency
• Restricted exhaust flow from a failing converter
• Emissions test failure caused by a worn catalyst
• Exhaust leaks at the converter connection points
• Noise or odor concerns from a deteriorated converter

Installation Notes and Tips

Compatible with 2007-2008 Honda Fit, direct fit. Verify the inlet and outlet flange style, O2 sensor port location, and overall length before installation. Transfer or reconnect the oxygen sensor as required by the vehicle configuration, and inspect adjoining exhaust components for wear or leakage that could affect the repair.

Fitment note: 2007-2008 Honda Fit, direct fit; Federal and California emissions listed in the fitment data. Not for sale or use on vehicles licensed in CA, CO, ME, or NY. Restrictions may apply in other states; check local regulations before installation.

Quality Assurance

AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment. The ARISTO substrate chemistry is used to support efficient catalyst loading and consistent converter performance.
