Dansk is the current OEM for the Porsche exhaust, & they sell those new, but not sure if you can get just the pipe, or if you need the muffler + pipe, etc.
Most Porsche parts houses & dealers will sell them.
I also saw a used 1.7 muffler & pipe on evilbay recently, if cost is an issue.
Bruce Stone/bdstone in SoCal & Rich Bontempi at HPH in Redwood City CA (SF Bay Area) are other sources for used parts like that.
Good Luck!
