Understanding the Role of the Catalytic Converter in Your FORTHING M4
The catalytic converter is an essential part of your FORTHING M4’s emissions system. It filters out harmful pollutants—like carbon monoxide, nitrogen oxides, and unburnt hydrocarbons—before they exit the exhaust. This makes your car environmentally friendly and keeps it compliant with local emission standards.
A failing catalytic converter can lead to:
-
Increased tailpipe emissions
-
Failed inspection tests
-
Reduced engine power
-
Poor fuel economy
-
Illuminated check engine light
When Should You Replace a Catalytic Converter in the FORTHING M4?
Typically, a catalytic converter lasts between 80,000 to 100,000 kilometers. However, certain driving habits, engine misfires, or poor fuel quality can reduce its lifespan.
Common signs of a failing catalytic converter include:
-
Rotten egg smell (sulfur odor)
-
Rattling noise under the vehicle
-
Sudden drop in acceleration
-
Trouble starting the engine
-
Diagnostic Trouble Codes like P0420
If you notice any of these symptoms, it’s wise to have the converter inspected and replaced if necessary.

Spray bolts with penetrating oil to loosen rusted connections.
-
Remove the old catalytic converter, disconnecting any oxygen sensors.
-
Install the new converter, aligning it with factory mounting points.
-
Reconnect sensors and battery, then test for leaks or engine codes.
Note: It is crucial to use OEM parts to avoid check engine light recurrence due to sensor mismatch.
Why OEM Catalytic Converters Perform Better Than Generic Replacements
Generic converters may be cheaper but often lack proper substrate density or fail early. Worse yet, they might not meet local emissions requirements, resulting in inspection failures or fines.
Benefits of OEM FORTHING M4 catalytic converters:
-
Perfect fitment with factory flanges
-
No tuning needed for engine sensors
-
Improved fuel combustion and engine efficiency
-
Longer lifespan and corrosion resistance
-
Compliance with global emission standards
How Much Does a FORTHING M4 Catalytic Converter Replacement Cost?
The total replacement cost generally includes:
-
OEM catalytic converter: $250–$400
-
Labor (if not DIY): $100–$200
-
Gaskets and bolts: ~$30
-
Optional oxygen sensor (if faulty): $40–$70

-
Vehicle registration issues
-
Failed roadworthiness inspections
-
Environmental fines
Our OEM parts ship with certificates of compliance, ensuring your vehicle remains road-legal in Germany, Spain, Poland, and other EU nations.
