The installation on my set didn't present any problems, but follow the manufacturer's instructions to the letter. If you don't have those instructions, then get them.
As far as the noise goes, I'm a crazy old gearhead from way back, and I could (and do) listen to straight-cut (aka "noisy") gear drive whine all the time. It's beautiful music, along with a choppy exhaust and that open-element air cleaner intake roaring. I don't even have a stereo installed, and it's not for lack of cash; I like to hear what I drive.
That being said, if a person has any doubts about whether or not they'd get tired of a whining gear drive - then they probably would get tired of it fairly quick. If you're not absolutely sure you want to hear it singing to you (and all your passengers) every second that the engine runs, then trade it off to somebody else. You don't want to take the time to install the GD, then turn around and swap it for a quiet chain a few months down the road, because you got sick of the WHHIIRRRRRRRrrrrrRRRRRRrrrrrrrrrrRRRRRing.
