AP Exhaust 642127 Catalytic Converter

AP Exhaust 642127 Catalytic Converter

AP Exhaust 642127 is a Federal / EPA direct-fit catalytic converter built for exact OE dimensions and fitment. It is engineered for 2007-2009 Honda CR-V applications and uses a ceramic substrate with a stainless steel body for dependable exhaust system replacement.

Key Features

• Direct-fit catalytic converter for confirmed Honda CR-V applications
• Federal / EPA direct-fit design
• Ceramic substrate material
• Stainless steel body construction
• 2-bolt welded flange inlet and 3-bolt welded flange outlet
• Two O2 sensor ports
• Overall length: 32 inches
• Outlet gasket included

Detailed Description

Built under AP Exhaust’s ARISTO manufacturing approach, this converter uses proprietary substrate chemistry and modern production methods to support efficient emissions control while maintaining OE-style dimensions. The result is a direct replacement for the exhaust system on 2007-2009 Honda CR-V models, with fitment coverage for Federal and California emissions configurations as listed. AP Exhaust 642127 is also a practical choice when you need a replacement catalytic converter that matches the original flange layout and sensor-port configuration.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Failed catalytic converter efficiency codes
• Restricted exhaust flow from a worn converter
• Emissions test failures related to converter performance
• Exhaust leaks at flange connection points
• Check engine light concerns tied to O2 sensor readings

Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering, since this part is listed for Federal and California emissions applications but is not for sale or use on vehicles licensed in CA, CO, ME, or NY. Confirm the inlet and outlet flange style, O2 sensor port count, and overall length against the original converter before installation. For best results, inspect adjoining exhaust components, gaskets, and sensors for wear before completing the repair.

Quality Assurance

AP Exhaust uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions and fitment. That manufacturing control supports consistent installation and repeatable exhaust system performance on the Honda CR-V.
