I had that setup for about a week until I had my long tube headers installed. It seemed quiet but I was coming from he stillen cbe and berk test pipes which was really raspy. The f intentions exhaust with test pipes was refined, deeper, and smoother like everyone says. But it was too quiet for my liking. I'm guessing its louder than the 12" with stock cats. Sorry I never took a video but I did manage to get a ticket trying to show up an Evo right after install
