Well, there isn't much to say here, and it doesn't look like I'd be able to warranty these through GTM since they don't seem to really exist any longer.
I rarely drive the car, and still only have about 7k on the supercharger (16k total).
As far as the test pipes go, they probably only have 10k miles on them and this is what has happened to the passenger side downpipe.
Any chance of repairing this? If not, anyone selling some resonated pipes at a good price
