I have a Powertrain Industries inc. 1 piece aluminum driveshaft. 5 years ago I paid over $500 for it I believe. The only noise or drone I have with it happens at speeds over 100 mph. I don't go that fast often. Driving under that speed I don't experience any inconveniences. I remember the weight of my aluminum driveshaft being a little more than half of the factory one. I'm happy with it.
