BMW M3 F80, M4 f82 Exhaust Tip removal - The proper way

I searched several videos on how to properly remove the exhaust tips on a BMW M3 f80. A lot of the ones I saw was guys with a hammer and a piece of wood, which is nothing wrong. During my search I ran into a video that was fast forwarded and it had a strange tool, you couldn't see it well in the video. After a few searches, I found out what it was. I ended up ordering it on Amazon for $30, and here is the video for anyone looking to do this task on their own. Reason for the removal was to paint them black.
