I have never heard of a test pipe for the C6. From what I know, when people list "Off-Road" pipes, it's for a car with headers, not to replace the stock cats. Also, I really doubt if you are going to find a pipe that will fit the 3 bolt flange on top and the right shape on the bottom.
If you really have to have one, go to a good muffler shop and see if they can fab one for you.
