Here is my question: I realize that sound quality will be different, but does anyone know what size resonator in the FI exhaust will best approximate the loudness (ie decibel level I guess), of the stock Z06 exhaust with the butterflies open? If no resonator, is the sound much louder?

Am think seriously about this exhaust but not sure about the resonator size.

the 12 inch
