Eastern Convertors 40686 Catalytic Converter with Integrated Exhaust Manifold - Front

Direct-Fit Catalytic Converter Manifold

Eastern Convertors DIRECT FIT Part Number 40686 is a Federal / EPA direct-fit catalytic converter with integrated exhaust manifold for select Mini Cooper front applications. It is built to OE dimensions for proper fitment and uses a standard catalyst design with two O2 sensor ports.

The DIRECT FIT product line focuses on exact-fit replacement parts for straightforward installation and consistent exhaust alignment. Part number 40686 follows that approach with a welded 4-bolt inlet, welded 2-bolt outlet, and a 34-inch overall length.

• Federal / EPA direct-fit manifold design
• Standard catalyst type
• 4-bolt welded inlet and 2-bolt welded outlet
• 2 O2 sensor ports
• 34-inch overall length
• Includes 1 inlet gasket and 1 outlet gasket

Fitment and Application Details

This catalytic converter manifold is made for 2002-2008 Mini Cooper front exhaust applications. It is a direct-fit replacement for vehicles requiring a Federal / EPA configuration and is not for sale or use in California, Colorado, Maine, or New York for vehicles with CA emissions. Part number 40686 is the correct reference when matching this Mini Cooper exhaust manifold converter assembly.

Common Repair Uses

• Replacing a failed catalytic converter on a Mini Cooper front exhaust system
• Addressing exhaust leaks at the manifold-to-pipe connection
• Restoring proper O2 sensor placement after converter damage
• Correcting emissions-related fault codes tied to converter efficiency
• Replacing a warped or cracked integrated exhaust manifold assembly

Installation Notes

Verify the vehicle’s emissions configuration before ordering, since this part is Federal / EPA direct-fit only. Confirm the 4-bolt welded inlet, 2-bolt welded outlet, and both O2 sensor ports match the original unit. Use new gaskets during installation and inspect the mating flanges, sensors, and exhaust hangers before final tightening.

Quality Assurance

Eastern Convertors uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to OE dimensions and fitment. The proprietary NANO substrate chemistry is used to support efficient catalyst loading and consistent converter performance. Part number 40686 is manufactured to the DIRECT FIT standard for accurate replacement on the listed Mini Cooper applications.
