Product Details

AP Exhaust part number 642041 is engineered for OE-style replacement on rear exhaust positions where the original converter has failed, become restricted, or no longer meets emissions performance requirements. The converter is built to exact dimensional standards and uses AP Emissions Technologies manufacturing methods to maintain consistent fitment and production quality. This part cross-references Monroe Shocks & Struts (e.g., 25800952) for the same application.

Compatible With 2010-2017 Chevrolet Equinox, rear, and 2010-2017 GMC Terrain, rear. It also covers 2010-2012 Chevrolet Equinox and 2010-2012 GMC Terrain applications listed without a position designation in the fitment data.

Common Replacement Reasons

• Failed emissions test or catalyst efficiency fault
• Restricted exhaust flow from a worn converter
• Rattling or damaged converter substrate
• Exhaust leak at the converter flange connection
• Check engine light related to catalytic converter performance

Installation Notes

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 the inlet flange style, outlet pipe size, and rear-position fitment before ordering. Professional installation is recommended to ensure proper sealing and alignment.

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 ARISTO substrate chemistry is used to support efficient catalyst loading and consistent converter performance.
