All Exhausts except CORSA magnify the inherent drone of a V10. Decibels matter.....only the volume and the tone changes. Some are worse than others. Magnaflow is a very recent product for GTS.....but has nothing engineered to address V10 firing pattern
Only Corsa is engineered to eliminate V10 resonance and drone.......
One problem here, is this: Some tastes dont care, or dont even HEAR the V-10 Drone. It is difficult for some owners to put their finger on it.
Those mnay of us who DO hear it, only hear it resonate annoyingly at certain RPM ranges..mine is 1800-2800, a prime crusing RPM range. But an ocilloscope clearly reveals it as a discordant frequency, made louder by all louder exhausts! But like a dog-whistle, SOME CANT SEEM TO HEAR IT. (Rock Concert Regulars?)
