If you are fanatic about JDM parts, you may have to do a bit of hunting around for the del sol... But on the other hand, although I have never used an xforce muffler I have heard good things and if you are just after sound you really couldnt go past xforce for price and availability.. based in Sydney aswell and in my personal opinion I would rather buy a branded exhaust that has history rather than go to an exhaust workshop and them grab a no name brand off the rack..
