I'm not concerned about the exhaust note....more interested in performance.

Hi aussieboxy
I am another Australian Boxster owner, first time posting, I've been a visitor for the last 18mths ever since I got my Boxster S.
As for your exhaust, personally I would leave the muffler alone and go with ebay extractors and cat bypass pipes.
I installed the ebay extractors about a year ago, a little more torque through the low to mid range, top end improvement is debatable. I just did the bypass pipes a week ago, had them custom made on a mandrel bending machine out of 50mm (2 inch) stainless to match the extractors. This did make a difference to the power that I could feel.
I hope this helps. Also, where are you in Aus? I'm in Perth myself.
