I held the ZZP ultra quiet resonator up to the end of my system and it noticeably quieted it down. Nothing super duper dramatic, but noticeable. Seemed to get rid of some of the deeper tones. I wasn't able to rev it and hold it there to fully test it, but I'm confident it will at least quiet it down from where it is now.
Also did some tests with a spectrum analyzer app on my phone about 5 feet from the exhaust. Its interesting to see the difference:
No ZZP
