dazla Posted September 3, 2007 Share Posted September 3, 2007 I've just recently bought my new supe and it has a stage 1 decat. Is this going to be ok with the mot? Quote Link to comment Share on other sites More sharing options...
Nic Posted September 3, 2007 Share Posted September 3, 2007 Do you mean only the first cat has been removed? If you still have the second cat fitted you should be okay. Quote Link to comment Share on other sites More sharing options...

Its the first decat thats been removed. Has any one else had any mot problems? Quote Link to comment Share on other sites More sharing options...
Wez Posted September 3, 2007 Share Posted September 3, 2007 2nd cat is normally enough to pass, some pass without any. Quote Link to comment Share on other sites More sharing options...
Nic Posted September 4, 2007 Share Posted September 4, 2007 The first cat is there to help reduce cold start emissions, MOT emission tests are carried out once the engine is up to temperature, so as Wes says you should be okay with just the second cat installed. This is assuming your engine is in good working order and your O2 sensor is not knackered. Quote Link to comment Share on other sites More sharing options...
