I think the bullit allready comes with underdrive pullies, so I wouldnt start there. Also, I think the catback is allready better than on a gt, so this is what I would start with.
1. offroad H or X. I have the Mac offroad H, it's cheap ($109), but if I had to do it again i would without question go with a Dr. Gas offroad X, It is a little pricey ($295), but well worth it in my opinion. The Dr Gas has to be welded to fit, and I know a place in Fort Worth that will do it pretty cheap, most places wont touch it because it dosent have cat's.
2. C&L 80mm Max Flow kit ($245). I picked up 9rwhp/10rwtq with this alone ( only got 11rwhp/15rwtq from the H and pullies combined).
3. Gears, 3.73's or 4.10's. My pick would be 4.10's.
4. Drag radials
my .02
