I don't have any Dyno Sheets saved from tests. I know there are a couple posted around the forums. Don't get me wrong, you can still make good power with test pipes. However, you will make more with the stock cats provided everything less it tuned properly. Now we haven't tested this with all the different cat-back exhausts out there and it is possible that some exhausts paired with test pipes would do better than the stock cats, but I can't say for sure.
