Short video of start-up, idling, and low revving of of my 2000 BMW M5 with Dinan exhaust.

This is a boring video I only made due to selling on BaT. That being said, people still randomly find it so a little more color commentary:

When I purchased it had a Flowmaster exhaust that was pretty quiet and kind of a janky installation. I bought the Dinan used and it was at least a cleaner install. That being said, it sounds better outside than inside. M5s have so much sound insulation you don't hear much at all inside the car and I would have preferred a louder exhaust just to hear some rumble in the cabin. IMO, not worth the money.
