The exit tube for the muffler sticks down into the body of the muffler. I drilled a small hole in that tube to allow some of the gas to go straight into the exit tube as it left the catalytic converter. There was no difference in performance and a very slight difference in sound. It's just a little deeper.
What did you change? Nothing?
