Morning Mannyo, I checked with the fitter before hand and had a good look over the new changes as long as the CATs in place i's all good, very thankful its pre dpf as those things are expensive

On second inspection of the new rules I may have to contact the fitter/ garage where I get my mot as I've now read noise suppression eg silencers, If thats the case I'm slightly annoyed at the fitter as he said there would be no issues

Checked with halfords all good phew
