looking for the QUIETEST gears!?
Pretty much all gear sets will be quite if they are setup CORRECTLY!! Lots of people complain about gear noise with gear changes,but most likely they are not set up right from the start and the gear set takes the blame for it, not the install setup.
Factory GM, and watch how you break them in the first 500miles, then change out your fluid. I had messed mine up the first time, I horsed on it, that was not good, do not do this.

Agreed.
My Motives are silent in operation from what I can tell - I set them up properly and gave them some break in time before really being mean to them though.

most street gears are the same...they are all pretty much cut the same (the teeth). like stated above for street gears it all depends on how they are setup and how u break them in. IMO I'd go with GM gears.

Agreed I agree that if the gears are set up properly then they will be quiet! I have Richmond 3.73's in my car (supposedly the loudest gear around!), and with the proper set up and break in period they are just as quiet as the factory gears. With less backlash left in them.

The money spent/involved is from finding someone who can set them up correctly and to increase your chances of a quiet gearset would be from you, following the proper break-in procedure.
I will also concur with those who recommended either OE GM or USGear.

I'll agree the install has more to do with it than anything, but gear quality will also be a factor.
Also, "proper break in procedure" has made zero affect in my gear installs. After the gears are heat cycled a few times, they are at WOT and it doesn't make a gear set any louder than one that's not been driven hard. Launching at the track though, that's completely different.

Now, I do agree about the hardness, but kinda agree with the surface finish. If you start out with junk, all you have is junk. But the surface finish has nothing to do with strength and or how quiet a gearset is goin to be. However, the heat treat depth has a lot to do with overall strength.
As for "a gear set or two"..... there is a huge difference between "a set or two" and a few of thousand. But, I dont expect you to know that.

I bought and setup some richmond's from Mark Williams that were given the "Supra-Fin" treatment. No break in time and they have been quiet for many thousands of miles. Kinda of expensive though. YMMV Give them a call they are good people.
Give them a call they are good people. Alright Chicane, I'm reading up on this as you very well may be correct on a few specifics. However, the break-in procedure I'm not sure I'll find a clear answer. Who picks the exact distance a gear set has to be driven before it's fully work hardened? I don't think there will be a clear cut answer to this one. Do keep in mind that I did say I DO use a procedure just not the standard "500 mile" procedure. My breakin consists of being easy of the gears and heat cyling them twice. After they've been ran and cooled a few times, I'll roll into the throttle (also no hard shifts), but they won't see abuse from sticky tires for atleast two weeks which would be more than the magical 500 miles.
Also, I haven't set up THOUSANDS of gear sets like you are implying you did. I've also never installed a gears into a Dana/Chrysler.
