They were both powertrain driveshafts, both aluminum as well. They are now building me a steel one, which previously was unavailable for twinturbos through that company, so if going steel makes more sense to you, thats an option now. But, in my opinion, with the power you will be making, you might wanna just stick w/ the stock 2 pc design. I cant see you risking breaking driveshafts for another 20 rwhp from a 1pc, lightweight design. Remember, 1pc driveshafts arent really recommended when the driveshaft angle is at more than a 5 degrees, ours is 4.5 i believe, so there is that stress on it already. Otherwise, when it was running, i loved it. I think its a great highway, daily driver, road race type mod, just not a great drag racing mod, for obvious reasons.
