Sorry to say this but I'm delighted.
My heart sinks when I see a tuned diesel go past chucking soot out at everyone!! OP I know this is not your car...but as usual these knobs ruin it for everyone.
Why should I get to taxed to hell on emissions while some guys removes his DPF for a few cheap HP!
So yeah, if in future people are going to fail for that, good news.
