I have read that their can be a specific problem with disintegrating valve seals and catalytic converters , see here;

Does seem a little unlikely in this case though . 2008 MY Supercharged

I know of several LPG cars that the CATS have died on and come apaert and rattle away in their case, you dont need CATS on a LPG car because there is no emission test for the MOT it is a visual test only, so im afraid in my ecperience it the garage trade is LPG does kill cats  One day your life will flash before your eyes......................................make sure yours is worth watching!

I've had 25 years running my own garage/workshop and been involved with all types of vehicles. And it's not a common LPG problem.

So have I Currently have a 10,000 sq ft workshop and we have had several lpg cars in with knackered cats and the % of LPG cars with knackered cats is far greater than petrol, coincidence, maybe but I had knackered cats too, is this a common RR fault? BTW see axles post and we had a 35ft V10 camper converted and the guy said we as well take the cats off and flog em before they broke up !!!! One day your life will flash before your eyes......................................make sure yours is worth watching!
