Fitment Details

Compatible With 2002-2006 Mini Cooper, N/A. This Dorman 673-862 manifold converter is matched to the OE-style exhaust manifold and catalytic converter arrangement used on these model years. It is a direct-fit solution for Mini Cooper owners needing a CARB-compliant replacement for the factory emissions component.

This part cross-references 452859 and 18407533402 for the same application.

What It Helps Address

• Failed catalytic converter emissions testing
• Cracked or leaking exhaust manifold assembly
• Check engine light concerns related to catalyst efficiency
• Exhaust leaks at the manifold-to-head or outlet connection
• Replacement needs after corrosion or heat damage

Installation Notes

Verify vehicle year and emissions requirements before installation. The square inlet port, outlet mounting hole pattern, and included gasket and flange components should be matched to the original exhaust layout on the vehicle. Professional installation is recommended to confirm proper sealing and sensor-related system checks after replacement.

Quality Assurance

Dorman engineers this manifold converter to match original equipment form and function on the listed Mini Cooper applications. CARB certification and Executive Order D-665-23 support use in regulated markets where compliant emissions parts are required.
