I know I know, the best performance mod is to sell my 3.0 and buy a 4.4 or 4.6/8, but I'm happy with the one I have and I'm not ready to trade up just yet. The color, condition, and options are exactly what I want and I'm surprised with how well it already performs.

Ok, now that I've overly justified myself what are some good ways to get a little extra? I've looked at exhausts, intakes, and ignitions, but I don't want to play guessing games based on my limited knowledge. Any suggestions???
