The strange thing with my Quaife installation was there was zero wine or any type of noise. It seemed quieter than stock.
I took it to the drags and after eight burn outs it was whining like a swine with flu. The wine would come and go on light pedal on or off. The higher the speed the louder the whine.
For those that asked the two pieces of the driveshafts bolted directly with no mods.
