If you're not worried about emissions, and a loud exhaust, there's gotta be a few pounds to lose by replacing the cats and mufflers with straight pipes.
Is the stock Driveshaft Steel or Aluminum? Any lightweight alternatives available?

I'm also interested in using the voltphreaks battery in my 2008 Viper. Anyone out there know if there is a potential downside to using this battery? Also, does anyone know what the actual stock Viper SRT-10 battery weighs? Thanks.
Removing weight can be a fun and rewarding endeavor. After all, it improves every aspect of performance. On my '68 vette, it was relatively easy to do because opportunities were everywhere. In those days, everything was built in cast iron. Even so, the car was only about the same weight as a Viper. A stock big block '68 vette weighs about 3450. I removed over 300 pounds already through the use of lighter components and will take off another 200 pounds before I am finished.
It is not as easy to remove weight from a Viper, especially the ACR, which already addresses some of the areas where weight can be removed.

rcl....I was in touch with Tony Hwang of voltphreaks. He believes we would need the 6 lb. voltphreaks battery for the Viper. Downside is that it does not have the amp-hour capacity and extreme weather (freezing) performance of the stock battery.
If you park the car and your stock battery runs down in a month, the voltphreaks battery would probably run down in two weeks.
If this isn't a problem for you, then the voltphreaks battery should be okay.
Don't touch the AC system. There are reasons why they did not offer that option and with the new computer system, it could cause you other issues --- couldn't get much more out of the engineers, but they said don't consider it at this time.

Thanks for the information. I think I will hold off on the voltphreaks battery for now.
No good for the Viper I assure you. I had one of these for my tiny turbo Miata, and it was trashed within 2 months. Go with another dry or gell cell.

If you absolutely need to have an adjustable seat I'd recommend the Cobra Misano (29 lbs) or the Recaro Sporster CS (32 lbs) over the Sparco Milano (38 lbs).
A fixed back seat would be the most beneficial with regards to weight. I'm not sure how much adjustability you can have in the Viper anyway. For a fixed back seat I'd recommned the Sparco Evo 2 (17 lbs for fibergalss shell, 10.5 lbs for carbon) or the Cobra Imola II (18 lbs).

Is that before or after he takes out the tire wall on turn 3?
Congrats on the purchase. Once the weight bottoms out, deleting the cats with a 3in exhaust and headers with a hard piping intake, plugs and wires should give the car some more snap.
