If I were you (and I wanted the most performance), I would put some 4.10's on your car. They will by far show the most improvement as far as pick up. You could also get any hi-flow system w/ cats. No matter how you look at the math, 2 cats is WAY better than the stock 6 (atleast that's what's on mine). But definitely, gears before exhaust. I went exhaust first--and it's not that I regret it, I just wish I would have done gears first.
