The fact that the cabin resonance is more of a "hum" compared to a deafening drone is great to hear.
Figure out how to email yourself the audio file from your phone and then upload it to the site or email it to me and I'll post it on the web for you and give you a link to use. PM me for my email address.
BTW guys, I have PM'd Flowmann and asked him to talk to the powers that be at Flowmaster about making up some of these units.
I will say this about sound clips of exhaust notes on the internet... they just don't do a good or bad muffler justice. Even a CGT doesn't sound all that great over computer speakers... if you're standing next to one or riding in one, you get the feeling of it deep in your chest though
I'm inclined to figure out how to get this setup for myself one way or another even if I've never heard it... just the lack of cabin resonance I have now would be a vast improvement.
