I will not drive it enough for that noise to ever get on my nerves.Can't wait to see a video of the Monster now.
That flutter will get on your nerves after a while. I had a Turbosmart BOV on my ecoboost. It made all types of head turning noises. Now that I've swapped out the exhaust and BOV to stock I actually like it better.
Granted...my eco is no Monster at all.
