Has anyone put or heard a dynomax super turbo cat back exhaust on a 3rd gen Camaro V8? Youtube has a few vids but are V6 Camaros. I don't want to get it on and then be disappointed. They are going for only $189 with a $75 mail in rebate, so it will end up $114 for a cat back exhaust. The price is appealing, but I am skeptical.
