Question about LT Headers...
Are they inherently street illegal, or is the legality based on the presence of catalytic converters? If someone could explain what makes pipes offroad, it would be much appreciated.
I know some states don't test emissions, but here in Georgia they do, and I didn't know if it was just a question of cats or no cats that made the difference.
