I have had both the full GT system and just the GT axle back on my car and can assure you that the axle back alone does not ring. All things aside I cant stand the look of the big round polished SS RPI muffler cans. It makes the car look to ricey from the back...

FYI the ringing sound is caused by the increase in exhaust velocity when the cats are removed. The original GT Muffler has a side inlet for the exhaust gas and it creates a ringing sound when the cats are removed. The new GTM mufflers have a straight through design, make amazing power, are loud as hell and drone like a mofo!
