These have been in the works for quite awhile, especially after GForce Engineering had developed an upgraded half-shaft set for Ford Racing to market for the S550 Mustang. Although there is another offering from DSS, these are unique since they are side-specific and are meant to cut down on axle hop. This has been something GM has been doing for many years (on the CTS-V, for example), so it's nice that Ford has finally caught on!
Here is their set for the '15-up IRS Mustang (Ford Racing M-4130-M):
I had written about the "anti-hop" technology (as GForce calls it) on my own site in this blurb on the half-shafts, and was glad to see those of us that had contacted them a year or so back about developing shafts for the Terminator had been heard:

In any case, their new shafts are technically still in a bit of R&D right now, but there is no doubt these will be a nice upgrade for the IRS Cobra (they'll also fit an earlier Cobra if the differential is upgraded to a 31 spline unit). I did talk to Casey at GForce about the axle diameters, and although to the naked eye the difference may not be obvious, they are definitely side specific (I think one has an OD of 1.385" and the other is 1.382"). More to come I'm sure, but here is the pic that is currently up on their site:
