I am not sure what information you are seeking, but for the Aluminum driveshaft, I went with a "Spydershaft" from Ron Leaonard, Leonard Racing Products
It's a high quality shaft with no adapters of any kind, Spicer HD joints, and cheaper than any other shaft i alooked at.
As far as the CAI, I went with K&N back in July of '05 and have been very satisfied with performance, quality and customer ervice. There are a lot of CAI kits out there I hope you get a lot of responces.
The question of CAI has been asked more times than you can shake a stick at. Do a simple search for CAI and I guarantee you will get more information than you can handle.
Why would the stock DS be a must to reach speeds of 140+? I would think an aftermarket aluminum shaft would be more than likely be able to handle 140+ if not made to.

The stock driveshaft has a center bearing allowing it to articulate with rear suspension motion and speed. This reduces the effects of high speed as well as mismatched pinion angles unlike a solid one piece which better be dialed in correctly or it would wobble and wear drivetrain components out quickly.

Nope... As said by walter, it has to do with the rear suspension, angles, etc.
squidd, a member of AFM, learned everything about the S197 driveshaft design in his quest to go over 200mph. He tried I think 3 different types of 1 piecers... He had vibrations on each one.
