Actually yes, it was the same event and runs were within a few hours of each other. A local club member had a stock GTP and I was curious. I didn't just make one run to confirm this, there were a few runs done to be sure. Just because you haven't actually done it to test it out doesn't mean you can be so quick to judge. I never said that the stock cat-back isn't "good" to that much FWHP, but you're absolutely wrong if you think that you will get NO improvement from a cat-back.
