i have a A/F ratio gauge sitting around from my old car and my car has a BBK catted X pipe, do they have the o2 sensors in the front?

Are you using narrow or wide band O2 sensors? An AFR gauge for narrow band has no meaningful output.

Actually, a narrow band AFR gauge does give you a little something. The "lights" bouncing back and forth show that your O2's are actually switching. Which is good.
