I know I can smash the insides of current one, however I think my flexi-joint is knackered anyway so am happier to buy the delete pipe instead. Problem is finding one for a PD engine.
This is the one I've had in my eBay watch list for ages, however the shop is empty now and seller away etc etc

These are the ones still available however it states 'not for PD engine'. I have emailed and asked if the sell them but they said no. But they look identical to me, am I missing something or can I use the polished one?
