Bellow Or Mellow
Billy Boat Performance Exhaust has released its Fusion bi-modal exhaust system for the C5 Corvette. Each of the system's mufflers is equipped with a pushbutton-operated butterfly valve that regulates exhaust flow. When the valve is closed, all of the exhaust travels through the "quiet" side of the muffler, allowing for a nice, mild exhaust note. When the valve is opened, the majority of the exhaust flows through the "loud" side of the muffler, emitting a deep, robust bark that's guaranteed to turn heads. Visit for more info.
