Fitment Details

Compatible with 2011-2013 Kia Sorento, rear, and 2010-2012 Hyundai Santa Fe, rear. This AP Exhaust 642829 application coverage is for Federal and California emissions configurations, with state-use restrictions noted for CA, CO, ME, and NY.

AP Exhaust uses proprietary ARISTO substrate chemistry to support efficient catalyst loading while helping control production cost. The converter is manufactured with automated workstations, spinner welding equipment, and high-speed production lines to maintain consistent dimensions and fitment for the listed Sorento and Santa Fe rear exhaust applications.

This part cross-references 28950-3CZK0 for the same application.

Common Problems This Part Can Address

• Failed emissions test due to a worn or inefficient rear catalytic converter
• Check engine light related to catalyst efficiency faults
• Exhaust restriction caused by a deteriorated converter substrate
• Exhaust leaks at the flange connection points
• Fitment issues when replacing the original rear converter on the listed vehicles

Installation Notes

• Verify vehicle emissions requirements before ordering, especially for state-specific restrictions.
• Confirm rear-position placement and flange style match the original exhaust layout.
• Inspect mating surfaces and replace damaged gaskets or fasteners as needed during installation.
• Check for proper exhaust alignment before final tightening to reduce stress on the converter body.

Quality Assurance

AP Exhaust manufactures this converter to OE dimension targets using controlled production processes and automated welding methods for consistent fitment and build quality.
