We made a few pre-production sets for testing purpose. Installed them on a few local cars and did some dyno testing.
The advantage was a significant weight savings and they were louder than stock. The dyno test showed no improvement in power which was expected. The sound quality was not what we were after. Further testing showed that the cats made a significant impact in that sound quality. Fast forward to today and it seems deleting cats is more popular than it was back then. Ultimately cost killed the project as at that time overseas aftermarket mufflers were dirt cheap.
To directly answer your question a few of these mufflers were sold at a discount for testing purposes but I have no idea where they are now. I've considered selling our 996 but folks today are willing to spend more money on these systems so we might take a look at that.
