Went to MIJ performance, the guys who fitted my custom downpipe / cat cos if it failed the emssions then they would have to sort it 😛
cost of MOT this month is £20
and the car sailed through and the emissions were around 10% of the limit so all good, 0.03 % or sommit
12 months MOT for £20
I cant remember paying that little since for a MOT since driving
