This is the closest I could get to a decent recording of it, it’s fairly quiet so cell phone audio doesn’t do it much justice. That being said, I’m very happy with the results. Noticeable bump in power (I suspect a good chunk of that is due to several horses that were escaping through holes in the previous exhaust being returned), but with no drone or any undesirables, and a bit of added sound to boot. It’s like Chewbacca playing a muted trumpet.
