1. what gears does this truck have?

Open your driver door and look for a sticker. The sticker will have an axle code on it.

These codes/ratios are what I have saved from another post... I'm guessing they are correct.

41 - 3.27 non-limited slip
45 - 3.55 non-limited slip
46 - 3.73 non-limited slip
42 - 4.10 non-limited slip
D1 - 3.27 limited slip
D4 - 3.73 limited slip
D2 - 4.10 limited slip

I drive the same truck as you special-k. My exhaust looks the same, but i don't believe one of the pipes is welded. I asked my buddy about running a dual exhaust on the truck in the past, but he advised me of the fuel lines being a little too close to where the second pipe would run on the driver's side...
