That's what I'm afraid of!

 

It definately has a chambered muffler sound. With the little bit of part throttle rasp I heard in the video thru a turbo, I think it is going to be much more pronounded in my setup. I probablly will not install mine unless I can find another muffler of the exact same length that I can easily swap out incase I don't like it. Thanks for putting up the vid and letting all of us that bought this kit know what it sounds like.
