At 131 the car will start nuclear fusion and glow like the sun.

I have a 3.5" Dynotech aluminum DS with auto and no vibrations at all. I installed it too. To not get vibration, you have to not only make sure the pinion angle is right but also install the new DS in the same orientation as the stock DS.

If I knew the 4" DS had nuclear fusion happening I would have done it a long time ago. While on the subject what do you think of the 1 peice. I'm borderline going F/I or staying NA. What do you guys think?

I think no matter what you are F/I or NA one piece seems like the way do go but they seem so damn expensive!!! you know you will always wonder what it is like to have 450 horses so might as well just do it and get it over with. JMO!!!!

you might as well do it right the first time just so later on down the road you dont have something fail and cost you alot more money than it would have been to just do it right the first time. learned this the hard way a couple of times, just not with the stang.
