Stock shafts are just fine for your HP. U joints are at all the vendors. And any local driveshaft shop could do the work for you if you feel challenged. CV is certainly going to deliver that WOW factor, but only to those of us that know there has been an upgrade. It really won't add any mechanical improvment.
I'd imagine you could spend your $$$ on many more valuable upgrades, functional or bling.
Not that I have anything against Dennis' product - sure you would be happy with it.
