B&B fusion cat back exhaust - Page 2 - ZR-1 Net Registry Forums

FYI, the drone we have all experienced in C4 ZR-1s is caused by two different frequencies that naturally occur at two different rpm points. The center resonator eliminates one and the rear mufflers eliminate the other. Don't know if drone is completely eliminated by other means if there is no center resonator; I would think not entirely.-Bob

As mentioned above, there is no resonator with this system. The X pipe and mufflers handle the drone. I purchased the full system with cut outs.
