I think you're spot on, much better flow. And the Borlas are a great sounding muffler.

I found that the x-pipe, for me, acted almost like true duals, seemed to lag a bit on acceleration compared to the H-Pipe. But I'm not running a huge HP motor so that's gonna have some affect as well... My 5.3 needed more back pressure
