I am in process of changing my XBR's Predator 2:1 exhaust to a 2:2. I have acquired a pair of new Black Widow "standard" downpipes and will need to marry these to a pair of silencers. XBR OEM are, of course, a little rarer than that rocking horse stuff and any that crop up are usually rough let alone stupid money. I'm hoping that someone might have some good experience/insight into fitting/using something suitable that will be very kind to the meagre amount I can spend after putting even more money aside for our energy supplier?
