Many people have been happy with AR design (both catless and catted) downpipes. You should come across many user reviews with a bit of browsing.
I'd recommend catted DPs OR catless followed by choice of your own hi-flow cat.
Also Adrian from Vishnu in Sydney will be able to advise on DP installers.
