Out of the two options you basically just need to decide if you want performance or looks. Personally, if it were me I'd go with performance. But I'd rather have a cold air intake, 4.10 gears, short-throw shifter, tune, full exhaust setup, (Longtube headers, X/H pipe, Magnaflows) and suspension mods. That's assuming you don't want to turbo/supercharge later.
