The ceramic substrate and calibrated construction support efficient exhaust flow treatment while meeting the requirements identified by Executive Order D-798-9.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

Common Issues This Part Addresses

• Failed emissions test due to a worn catalytic converter
• Check engine light related to catalyst efficiency codes
• Restricted exhaust flow from a deteriorated converter
• California emissions compliance replacement needs
• Front exhaust converter replacement on a Honda Fit

Installation Notes

Compatible With 2009 Honda Fit, front; and 2010 Honda Fit, front. Verify flange style, O2 sensor port location, and emissions requirements before installation.
