I have the Sebring Dual Tip exhaust and X pipes, if I was gonna buy another I would get it with resonators. I also have test pipes and downpipes so its loud but not unbearable, not bad at all actually. X pipes are what SpecialtyZ recommend, they supposedly flow better then H-pipes, you can search TT.net for info on that. The craftsmanship on the exhaust is top notch also, as good if not better then the Greddy PE exhaust on my old TT.
