What you see on these pictures is a BMR carbon fibre driveshaft
for my car compared to the stock driveshaft that comes with these cars.
The sock driveshaft was 7,175 KG (15.81 pounds).
The CF driveshaft was suprisingly heavy : 5.925 KG (13.06 Pounds).

If you are thinking about buying a CF driveshaft,and you want to reduce
rotating mass on your driveline, you shoud concider another make ...
for example ACPT.
The ACPT shafts are aluminum bonded ends and 100% carbon fiber shaft tube.
The BMR shafts are just carbon fiber wrapping around aluminum tubing to reduce vibrations.
I got this info from someone at the thirdgen.org message boards.

Weight of common f-body driveshafts:

16 lbs - Stock steel LT1 driveshaft
12.2 lbs - 3rd gen aluminum 1LE driveshaft
12 lbs - LPE aluminum driveshaft
11.5 lbs - Stock aluminum LS1 driveshaft
10 lbs - RK Sport aluminum 1pc driveshaft
4 lbs - ACPT carbon fiber

Here is a picture of the installed driveshaft.
