OEM Part
OEM: Made by an Original Equipment Manufacturer. This part is made by an original equipment manufacturer or under their license, ensuring compatibility and quality.
Exhaust Manifold with Catalytic Converter is a combined exhaust assembly that integrates the exhaust manifold and a type-approved catalytic converter into a single unit for the 1.8L K-Series (18K4F) petrol engine.

It bolts directly to the cylinder head exhaust ports, collecting the exhaust flow and routing it through the integral catalyst before the downpipe. The one-piece design replaces the separate manifold and catalytic converter arrangement used on this engine.

Frequently asked questions

What is the WCJ101440L exhaust manifold with cat?
It's a combined exhaust manifold and catalytic converter for the 1.8 K-Series (18K4F) petrol engine, built as one unit. It bolts to the cylinder head exhaust ports, collects the exhaust flow, and routes it through the integral catalyst before the downpipe.
What does the one-piece manifold and cat replace?
This one-piece design replaces the separate exhaust manifold and catalytic converter arrangement used on the 1.8 K-Series (18K4F) engine. Combining both into a single casting means you renew the manifold and the type-approved catalyst together as one exhaust assembly.
What are the signs this manifold or cat needs replacing?
A combined manifold and cat typically fails through cracking of the manifold casting or a blocked, deteriorated catalyst. Symptoms include an exhaust blow at the head, a rattle from a broken catalyst substrate, or a flagged emissions fault. Renewing the unit restores exhaust sealing and flow.
