Detailed Description

AP Exhaust 642220 is engineered as a direct replacement catalytic converter for rear exhaust locations on the listed Saturn Vue, Chevrolet Equinox, Pontiac Torrent, and Suzuki XL-7 vehicles. The ceramic substrate and proprietary substrate chemistry are used to support efficient catalyst loading while keeping the converter built to OE dimensions for proper alignment with the exhaust system. Automated manufacturing processes, including spinner welding and high-speed production lines, help maintain consistent fit and construction.

This part number is a practical choice when replacing a worn or failed rear converter on a 2008-2010 Saturn Vue or 2008-2009 Chevrolet Equinox. AP Exhaust 642220 also serves 2008-2009 Pontiac Torrent and 2007-2009 Suzuki XL-7 rear applications with the same direct-fit format.

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

Common Problems This Part Can Address

• Failed catalytic converter efficiency codes
• Restricted exhaust flow from a damaged converter
• Rattling or broken internal substrate material
• Exhaust leaks at flange connection points
• Emissions test failure related to the rear converter

Installation Notes and Tips

Verify the rear position, flange style, and O2 sensor port count before installation. Confirm emissions requirements for your state before ordering, since this Federal / EPA direct-fit converter is not for sale or use on vehicles licensed in CA, CO, ME, or NY. Use the included inlet gasket and inlet hardware as needed during installation, and inspect the mating exhaust surfaces for damage or corrosion before assembly.

Quality Assurance

AP Exhaust uses OE-dimension manufacturing methods and automated production controls to help maintain consistent fitment and converter construction. The ARISTO substrate chemistry is used to support efficient catalyst loading and converter performance within the intended emissions application.
