Opinions about slant 6 decal

I came up with a design a couple of years ago very similar to your 2d illustration. I used the Dodge Scat Pack bee as the basis of my design with a couple of extra pipes cloned in. If your car is going to be old school, I prefer this design.

If you're going new school, like using 17" wheels, I like your first illustration with pipes on the drivers' side and no magenta disc.
