This is directed to anybody that has installed Flowmaster mufflers on an '05 or '06 GT. I am considering Flows for my new '06 GT 'vert. I have heard the sound clips and they sound great, but do they sound good inside the car? My '06 is so quiet, I really can't hear the nice GT sound. I don't want "drone", but I would like to hear that nice growl. Help a brother out.
