Whats the "DIFF"erence?
Whats the "DIFF"erence? While installing my Borla the other day noticed the diff cover. Its much different than other fbodies I have owned. This one came with the Auburn diff. Whats the big difference? I will tell you that this one makes ZERO noise and their is no HOWL like all of my others...

When you say "came with the Auburn diff" I assume you mean originally? If so, that would be the Auburn rear which was optional via SLP on the SS models.
The Auburn LSD is different from the Torsen style that would have been standard for your model year. Both are limited slip differentials, but the Auburn is a cone/clutch style while the Torsen doesn't use a traditional clutch pack or cone setup.
FWIW, the Auburn style was the standard LSD offered in 4th gens prior to 1999, in that model year GM switched to the Torsen style. My '98 came stock with the Auburn, and I agree with the fact that it's always been super quiet compared to the Torsens in my '99-'02 cars (all of my Torsens have chattered under the same sort of conditions, even when the cars were brand new). I've never owned an F-body with the SLP upgrade Auburn LSD, so I'm not sure how this version might differ from the base Auburn rears of 1998 and prior (though my guess is that it's probably a higher bias version, and/or contains other enhancements).

Well it should be better as it was an $899 option according to my SLP upgrade list.
