I ended up buying them and had them installed 2 weeks ago. They sound amazing but have a drone at about 2800-3200 RPMs, but I don't really sit in that range very much. The drone is pretty bearable if you don't have a headache. I don't have a proper exhaust video, yet. Only a cold start and idle. Listen with headphones or a bassy speaker if you can.
