The Gen3 Fusion exhaust for the C7 Corvette is the result of Billy Boat's extensive development over the last six years of NPP exhaust development. We have learned a few things, and we have incorporated them in the Gen3.
* Uses the exclusive 3" butterfly valve at both the front and rear of the system. (factory is 2.5")
* The 3" side is truly straight through for more volume at idle, cruising, and head turning under acceleration.
* While it maintains all the modes of the C7, it turns them up a notch for true driving enjoyment.
We use our experience in bi-modal muffler design to further enhance the factory system
