Hello, me again 
You don't need an HKS one - in fact, you may well not want one (they're not very good
) - to go with something as free-flowing as the Hiper, it's worth getting one that doesn't block the wastegate - bellmouth, split bellmouth or twin dump, it doesn't really matter! 3" all the way through would also be good if you're planning on going nuts later (the Hiper is 3" straight through - the 'standard' is 2.5", which will mate up to the Hiper perfectly well). 2.5" is fine, though, if you're not planning on changing the turbo or anything at any point...
