^^^ Well, that is literally on paper so, you cant argue it didn't happen but, I've seen more change in back to back dyno runs where nothing is different so, could have been a fluke. I'm personally really anxious to get one of these to see if the ride quality gets better. Where are you guys going to get a driveshaft balanced?

Thanks for the link. The Bang for the Buck chart is very interesting:

Wow, with my cold air, Magnaflow muffler, airfoil, DS and the TB bypass I'm going to do later this week, I might be close to 300 rwhp with less than $300 spent.

Damn it's 18 lbs. lighter? I did mine a few years back, guess I've forgotten.

Default Wow, what a difference!

All I can say is wow. I didn't think a simple change like a aluminum driveshaft could make that big a difference. I finally got the change to really wring my new DS out today and it's like a new car at high(er) speeds, as smooth as my 2006 Grand Prix w/SC, but a helluva lot quicker getting to that speed. Plus the shifts are lot smoother and for some reason, quieter, that's why I think people say it seems acceleration is better. Maybe my case was a little worse because when I was changing my out my steel shaft, a little piece of rusty metal (weight?) was laying inside the torque arm.

So my NEW list of favorite cheap mods for LT1's is:

1. Skip Shift (mandatory) $12
2. LS1 driveshaft $75
3. Shocks (KYB AGX) $350
4. Magnaflow muffler $100

All of the above made an immediate, noticeable difference.
