You may well be right -- I doubt the seller of the ebay x-pipe did much R&D. On the other hand, designing a midpipe for a V8 is not rocket science (look in a Summit or Jegs catalog) and all the available x-pipes are pretty similar, with minor differences such as resonators or converters or none and different locations for the x section. Did all the available x-pipe makers rip off the designs from one another?
Was referring to your comment regarding Supersprint headers.
