I like the hood decal, but not the side decals. I never liked them on the V6 Mustang. I prefer the sides bare and clean. The reason being the stripes don't look complete because they don't continue on the front and rear bumpers
Actually I believe it is a "Mach 1" decal. Americanmuscle.com has them specifically for the GT and in the description it says "Mach one hood decal. Fits 2000-2004 Mustang GT". So I think its more of a Mach 1 styled decal for GT owners.
