Measure it...

If it's the same height and looks the same, I wouldn't worry about the color...

its just the zinc coating, which can vary from silver to gold to rainbow-ish depending on the coating thickness, which varies with each batch

Is the inner diameter of the z-tube actually bigger than the g-tube? Or it just mainly for sound?

Same ID. The Z tube doesn't have the resonator that the G tube has, which allows the induction of less turbulent air.

I got one of these from a friend, and the one I ordered just arrived today.

If anyone wants this one (brand new in the box) PM me. I'll sell it a bit cheaper then I got it for, and if not I'll send it back.

I have the velocity stack in my 05 6MT. Not sure of the opening though, looks to be about 1.5" though.
