Hi all just a question i have a skoda fabia 2011 vrs mk2 and currently running a jetex exhaust system and thinking of getting it res deleted and also back box but not too sure if it’s mot friendly or not (nothing wrong with my system just wanted it a little more noisy) thanks all 

Jetex will have gone to a lot of trouble making sure the exhaust system meets the noise regs while providing the maximum performance increase.

 

There is no chance whatsoever that deleting either or both of the boxes will pass the 74db MOT noise standard.

 

Don't bother, you'll just create an illegal plod magnet which will fail the next MOT and annoy all your neighbours as well.
