So my driver's side driveshaft has recently started making a racket, so I am just going to replace both sides but was wondering if there are any uprated ones available? 

And if possible, what sort of prices would I be looking at for an OEM in comparison. eBay has a fair few on there, but most are second hand.

I spotted your post aout having a failed wheelbearing and as it seemed to be quite fubar (making a lot of noise) i dare say the play /heat from the wheelbearing probably caused the outter c.v to fail too .

Cheaper options would be a new outter c.v or Icp sell new none oe driveshafts at a reasonable price. Either way i probably wouldn't bother changing both sides unless you're fitting a bearing on the other side at the same time.

You can upgrade the shafts and hubs to newage sti r180's but Standard classic r160 driveshafts are probably the weakest in the turbo subaru range and they're good for over 400hp . So it might be overkill

Pedders are now doing driveshaft kits,

I know they are available for the fox so I presume they will be available for other models, if they are made as well as the suspension they should be a good bit of kit
