My brother has had the cat converter stolen off his 2002 Peugeot motorhome. The van is on his driveway and he only found out when he moved the van to get ready for a trip away. The pipes were neatly cut either side of the cat probably using a cutter like the one used for cutting copper pipes. The police said the local g.......s ( fill in the gaps) target motor homes and 4x4 cars as they can crawl underneath with no jack. My brother has got a new cat and has welded on a bottom cover to make access harder and also welded on some steel bar onto the pipes either side of the cat so that they would have to use a hacksaw rather than a pipe cutter. We will see how effective this will be!
