C6 Replace factory NPP with more aggressive muffler

I have a 2013 GS with the NPP factory installed muffler. I have added a "mild to wild" remote so that I may cruise in either quiet or loud mode at will. However, I am still not happy with the sound. My previous 2007 Vette did not have the NPP, and I installed a set of Magnaflows which were loud 100% of the time.

I am looking into modifying the exhaust with a B&B Fusion muffler system which (they claim) is ready to accept the NPP connection. They call it a 'bolt on installation' (whatever is meant by that). B&B also claims that with the butterflies closed the system is slightly louder than the present stock, and with them open, the sound level increases quite noticeably.

Has anyone modified their NPP system, and with which product ?

Thanks,
