Here is a quick "video" of the exhaust:
Unfortunately the video is just audio over still images. It was simply too dark for real video. Even at ISO6400, f/2.8, and 1/30sec shutter speed it was still nearly black. I had to use long exposure photos and the audio from the video clips.
As you can tell, this exhaust has a pretty mild sound signature. Especially paired with the EL headers it is very quiet inside the cab. It has zero drone at all. There is a little more noise outside, but it is not loud. The fit and finish is great, and the tips look amazing!
