I've been wanting to do this for some time now but just haven't gotten around to it. It's my attempt to capture the Full Challenge exhaust note with Sport X-Pipe on my 2012 E92. I filmed it on Long Island using the Drift Ghost-S cam with external mic, which is a notch better than the built-in mic. You can hear where it comes up short during some footage, but overall did pretty well given the task. Should I have used a better aftermarket mic for a sound reference video? Probably. But being cooped up all winter, I was itching to get out and do something M related! You get it.....
With that, enjoy
