ST Stainless Decat pipes  
 

There seems to be a lot of confusion surrounding what a 'Cat' does, what happens when you remove it and the MOT requirements.

Here are the answers:-

bullet

The catalytic converter (CAT) helps to convert carbon monoxide into carbon dioxide. It converts the hydrocarbons into carbon dioxide and water. It also converts harmful nitrogen oxides back into nitrogen and oxygen.

bullet

The lambda or O2 sensor, is the key sensor in the engine fuel control feedback loop. The ECU uses the O2 sensor's input to control the amount of O2 in the exhaust gases and balance the fuel mixture, keeping it within a very narrow Air/Fuel ratio band of +/- 0.03% of 1.0 λ

bullet

The O2 sensor is fitted in the exhaust before the CAT, so removing the CAT will have no effect on the function of the O2 sensor, fuel mixture or the running of the engine other than to let it breathe better.

bullet

The current MOT test does not include a gas analyser check and as far as we are aware it will not be introduced in the near future, so you are quite within the law to remove the CAT in the UK.

 

All our Decat pipes have provision for lambda O2 sensor where fitted as original equipment
