I know one of the best things to do for our cars is a tuner; i have one and love it. With the exception of a s/c, no other mods seem to have the benefits of a 1 piece DS.Possible .2-.3 in the 1/4 seem to be thesame gains or better than intake/tune. So...why are more 1 piece aluminum driveshafts not being used? I know there is more talk about them lately, but what are possible catches to getting one. There are not any for the intake and tune, but for the DS:

1. if not properly balanced... well, it just sucks

2. uncovers other noises/inperfections in the design of stang

What else is there? Either from people that have em now, or people like me who have done some research but dont have experience.

Thanks,this mod seems to have some good bang for the buck.
