Product Details

The Walker EPA Ultra Direct-Fit Catalytic Converter line is built for import and domestic OBDII vehicles and focuses on direct replacement fitment with EPA-standard compliance. Part number 16687 uses a round stainless steel body, a 3-inch outlet inside diameter, and a ceramic substrate to match the exhaust configuration on the supported Mini models. This part cross-references Eastern Catalytic 41022 for the same application.

Compatible With 2007-2015 Mini Cooper, front; 2011-2016 Mini Cooper Countryman, front; and 2013-2016 Mini Cooper Paceman, front. For Mini Cooper and Mini Cooper Countryman applications, the fitment notes specify federal and California emission models, with state-use restrictions noted for California and other CARB-compliant states.

Common Repair Applications

• Check engine light related to catalyst efficiency codes
• Restricted exhaust flow from a failing converter
• Emissions test failure caused by a worn catalytic converter
• Exhaust noise or odor from a damaged converter assembly
• Replacement of a rusted or deteriorated front catalytic converter

Installation Notes

Verify the inlet and outlet flange style, oxygen sensor locations, and front-position fitment before installation. An exhaust gasket is recommended for the Mini Cooper and Mini Cooper Countryman applications listed in the fitment notes. Confirm local emissions regulations before purchase, especially for California and other CARB-compliant states.

Quality Assurance

Walker EPA catalytic converters are designed around EPA compliance requirements and direct-fit replacement geometry for the listed vehicles. Part number 16687 is intended for the specified Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman applications only.
