Do you know what gear ratio is in the rear end?

I was just curious cause mine has 3:55's and I hate it.

There isn't really any options for us as far as performance mods.

But to half way answer your question I have heard the stock intake system with a good drop in filter flows just as well as any aftermarket CAI

I don't know if 3:21's were available in 2011 I think it's either 3:55's or 3:92's
