What is dual mode exhaust?
it is operated by a vacuum control. Essentially, at 3500 RPM the valve automatically opens to partially bypass the mufflers and make it a 'straight back' exhaust, giving more free-flow and sound for spirited driving. when open, it's a straight-through exhaust...very little muffling, very little restriction. When it's closed, the air and vibrations is diverted through a more traditional muffler setup, which tames the sound.
