The catalytic converter is a key component of the exhaust system, designed to reduce polluting emissions by transforming harmful gases into less dangerous substances. However, it can also limit engine performance. The Decat (Cat Off) option electronically disables the warning light linked to the catalytic converter when it is removed.
Decat removal consists of electronically disabling, via ECU reprogramming, the alerts and error codes related to the catalytic converter. The engine is then freed from its restrictions, improving performance and responsiveness.
The catalytic converter plays an essential role in reducing harmful emissions (CO, NOx, HC). Its removal can improve power and exhaust sound, but it is strictly illegal on public roads in most countries, except for competition, export, or industrial use.
Eliminates error messages and dashboard lights related to the catalytic converter after its removal.
Improves engine management and responsiveness, especially after other modifications.
Prevents clogging-related issues with the catalytic converter and lowers maintenance costs.
Frees the engine from catalytic restrictions, delivering better performance and a sportier exhaust sound.
No, it is illegal on public roads. It is only allowed for competition, agricultural, industrial, or export use.
No, mechanically the engine is not harmed. In fact, it often runs more efficiently without the catalytic converter, but emissions will increase.
You send us your ECU file through our platform, our experts electronically disable the catalytic converter warning, and then you re-inject the modified file into your vehicle.
Catalytic converter removal is a popular modification among performance enthusiasts and tuners. It improves throttle response, eliminates dashboard warnings, and optimizes ECU management. However, it increases pollutant emissions and remains illegal on public roads.
