I'm loving my Zoomers. Loved it before headers, love it after headers and I think it is going to sound fantastic when I install the cams. No it's not crazy loud but I want to be considerate when it comes to my neighbors with small children. It still sets off the neighbors car alarm when I first start it and if I don't idle when I go by his vehicle, it sets it off again, lol. It is just loud enough to know it is absolutely not stock but quiet enough not to attract unwanted attention. I got to compare it to a Titan with the JBA on it and to me the JBA sounds like a big mean popcorn machine where as the Zoomers only pops if you bring it to red line and let off abruptly.
