I also bought a Shaftmasters aluminum driveshaft and hope to get it on the car tomorrow. I put one in my '11 GT and it definitely made the car 'snappier' and more throttle
would a tune help out with throttle response as well? As far as the DS goes don't forget the speed issue everyone talks about. There's only been a couple instances that I've heard of but one was on a dyno and the whole thing just tore. Personally I think it would be a smart thing to do, but after you get an intake and tune.
