V6 - 3.09 final
GT V6 - 3.29 final
GT adds bling (chrome) along with specific wheels and as mentioned, the tapshift transmission which was the selling point for me.
I'm not an ass man, so I can't say for sure what my exhaust tip looks like. As long as they remain functional, that's all that matters.
The V6 for 2007+ models gained about 20hp and a few pound feet of torque.
