Hi all, i'm looking to get some clarification on the subject of emissions and cat converters when getting MOT's for the 2.0tfsi engine.
If one was to fit a full exhaust system without a cat would the car fail on the missing cat or the emissions being outside the parameters or both, but, if the emissions were within the test range would the failure only be due to the lack of a cat.
So then if the car had the same setup and was then remapped would the emissions then be within range comparable to factory parameters.
I know this may sound strange but I have noticed a lot of owners fitting full systems with no cat and still getting throught the MOT test.
Full systems with sports cat are obviously already made to work from the box but what about non cat setups.
