What does DECAT involve?

It adapts the ECU for an existing catalyst-free setup within a permitted use.

What information must I provide?

Provide the file, exhaust and sensor setup, AFR, diagnostics and intended use.

Is this service suitable for every vehicle?

No. ECU, engine, exhaust and especially local law must all be compatible.

How is the result validated?

AFR, DTC logic, temperature and exhaust sealing are checked in a controlled test.

DECAT supports a hardware exhaust change on a dedicated vehicle setup. The catalyst is emissions-control equipment: removing it is not a repair and is generally incompatible with public-road use.

What this service delivers

Setup verified

Exhaust, sensors and engine calibration are considered together.

Targeted adaptation

Relevant strategies are treated for the exact ECU.

Risks stated

Thermal, noise and regulatory constraints are documented.
