Which is louder? Flowmaster 40's or Delta Flow?

I just got Flowmaster 40's on my 2001 GT. They are pretty freakin loud But does anyone know if the Flowmaster Delta Force Race Mufflers 1 Chamber is louder than the 40 series?

Well, i would imagine so.

2 chambers are louder than 3's, so i would imagine 1's would be the loudest
