Why can't they fix/weld the split? You have a factory Porsche Sports Exhaust which is very expensive (about $3200 from Porsche right now). It is one piece, and you cannot buy the tips separately. The "super sound tips" you are referring to work with the Dansk sports exhausts that can be bolted onto the Dansk exhaust without the tips (made to accept varied tip designs), or one that is pre-welded on the Dansk (as I have on my car below). They are not made to work with your factory PSE, but maybe a welder can help you to adapt it somehow. Here's what the tips themselves look like (as you can see, they are not made to accept the two pipes coming in from the sides):

Alternatively, if you like the look of those tips, you can buy what I have and have it installed...it will have a similar look, but without the long pipes feeding the tips. Designtek also rebrands the Dansk exhaust, and sells it closer to where you are located:

Something else that MIGHT work (although I'm not sure of it cause I never tried it) is for you to buy a used 2003/04 factory exhaust (which allows for tips to be bolted on), and then you buy the dansk super sound tips (tips only), and try to bolt them on the factory 03/04 muffler. That could be your cheapest option if it works. Good luck.
