I had always wondered if it was just mine, I feel a lot better knowing its common. I do like the S/C like sound though. When you drive it through parking structure, the combination of the whine and the exhaust make it sound like an absolute beast!
I had wondered the same thing. Everywhere I looked told me the 18 PP A10 had a Torsen 3.55, but it wasn't called out on the window sticker that way, however it was clearly stated as Torsen on any 18 manual PP window sticker.
