Installation Notes

Confirm the vehicle’s emissions label and application details before installation, especially for California-compliant use. This converter uses 2-bolt welded flanges at both ends and does not include O2 sensor ports, so the existing exhaust and sensor layout must match the listed application. AP Exhaust 772457 is a direct-fit replacement for the specified Hyundai Elantra, Hyundai Sonata, and Kia Forte rear applications.

Quality Assurance

AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment standards. The substrate chemistry and manufacturing process are used to support efficient converter performance and consistent production quality for emissions-controlled applications.
