Will be doing the turbo exhaust soon, but I am undecided on what size to go, 3" will drone won't it, at higher revs, gives off droning sound which drives you insane, but at the same time is flowing a lot better than a 2.5", the 2.5" won't drone as much, but maybe not flow as good? The turbo exits via a 3" dump pipe, so would be better to keep it 3" all the way through? or go 3" to muffler and 2.5" out? Car is XF Falcon.
