What This Converter Helps Address

• Failed emissions testing due to a worn or inefficient converter
• Check engine light concerns related to catalyst efficiency
• Restricted exhaust flow from a deteriorated substrate
• Rust or damage to the original converter housing
• Fitment issues when replacing a California-emissions front left converter

Installation Notes and Tips

Verify the vehicle’s emissions label, engine configuration, and front left placement before ordering. This unit uses a 4-bolt welded flange inlet, a 3-bolt welded flange outlet, and two O2 sensor ports, so confirm sensor and flange alignment against the original part. For best results, inspect mating surfaces, gaskets, and exhaust hangers during installation.

This part cross-references Walker (e.g., 16467, 16468) for the same application.

Quality Assurance

AP Exhaust builds this converter to OE dimensions using automated manufacturing processes and spinner welding equipment to support consistent fitment and repeatable assembly quality. The unit carries Executive Order D-798-9 for the listed California-emissions applications.
