Don't know, never heard the Rush. I'm guessing they're the same pipe though. I know that Rush makes the pipe for Frank and the Wrath is pretty much the exact same description as the Dragula. I LOVE this pipe. It sounds nice and deep, with a good bark during acceleration. The key for me though is that when you're at highway speeds, which is when I just like to kick back and listen to the stereo, it settles into a nice tone just a little bit louder than stock.
