Buying a performance exhaust system can be a purchase motivated by numerous factors. Of course we’re all after more horsepower, a more assertive tone and just the right sound profile. It can be an arduous guessing game sifting through videos and sound clips to confirm what you’re buying will meet your exacting needs.
Billy Boat exhaust is taking some of the guesswork out of the equation by answering some fo the most important and frequently asked questions about their Z06 Fusion Alxle-Back exhaust system. “How loud is this exhaust?” You might ask. Well as so many OEMs are making the shift to bi-modal systems so is the performance aftermarket. Billy Boat includes a butterfly valve inline to control the bi-modal volume control.
Now, depending on your driving style the bi-modal feature either keeps the exhaust a reason burble for cruising comfortably, or opens up for an aggressive volume comparable to a Billy Boat Bullet muffler. As Billy Boat puts it, “you get a ‘Dr. Jekyll’ cruising sound, and release the ‘Mr. Hyde’ Bullet Exhaust sound when you want!”
Depending on your application the butterfly is controlled by a vacuum signal or the ECU, so there are no switches to wire, just drive how you want and the exhaust system will take on the personality to suit your style. C7 Corvettes can also benefit from 18 hp and 17 lb-ft of torque while adopting a new deep and aggressive sound/
Ensuring long-time good looks and exacting quality control, the Fusion system is fabricated in the USA from mandrel-bent, TIG-welded 304 stainless steel.
