Product Details

AP Exhaust 641503 uses ARISTO substrate chemistry and AP Emissions Technologies manufacturing methods to support efficient catalyst loading and consistent converter construction. The design focuses on OE-style fitment, which helps maintain proper exhaust routing and sensor placement on the Honda CR-V. This part cross-references Honda OE number 18190R5AA00 for the same application.

Compatible With 2012-2014 Honda CR-V, front and N/A positions as listed in the fitment data. AP Exhaust 641503 is a direct-fit replacement for drivers needing a Federal / EPA catalytic converter for these model years.

Common Problems This Part Can Address

• Failed emissions test due to a worn catalytic converter
• Check engine light related to catalyst efficiency codes
• Exhaust restriction from a deteriorated substrate
• Exhaust leaks at flange connection points
• Incorrect fitment from a non-OE-style replacement converter

Installation Notes and Tips

Verify the vehicle’s emissions configuration before installation. This part is listed for Federal and California emissions applications, but it is not for sale or use on vehicles licensed in CA, CO, ME, or NY, and restrictions may apply in other states. Confirm O2 sensor location, flange style, and overall exhaust routing before beginning the repair.

For best results, inspect mating surfaces, gaskets, and nearby exhaust components during installation. Proper alignment at the front position helps reduce stress on the exhaust system and supports a secure seal.

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 stainless steel construction and ceramic substrate are selected to support long-term exhaust service in the Honda CR-V platform. AP Exhaust 641503 is engineered as a direct-fit emissions replacement for the listed applications.
