Seems Z1 Motorsports sells an OEM Q50 Resonated Sport Muffler with these built in. The original Nissan design has these drone eliminating resonators built in.
Too bad that aftermarket exhaust manufacturers don't consider doing the same thing for exhausts that they 'know' are going to drone (and most do btw). That would take some R&D to research the sizing and all, but they'd have some happy customers that would be putting aftermarket exhausts on and not dealing with too much drone and the accompanying buyer's remorse; https://www.z1motorsports.com/exhaust-piping/infiniti/oem-q50-resonated-sport-muffler-kit-p-10538.html
