Insure a decat

[RetroPug]

I don't see why people are so worried about insurance refusing cover if you declare it to a specialist. If you run a red light (illegal) and have a crash your still insured aren't you?

Me personally not worried about insurance cover. But my point is we don't need dpf's like we don't need Egr's they just something else to go wrong so if you making engine as efficient as it can be why should that be classed as a mod

Classing something as a modification has nothing to do with how sensible or not it is, it is simply as the name suggests, a change made to the car that makes it different o original factory spec.
