I understand about the big gap thing. But a black pickup with 3 inches suspension lift and 2" body with 33" X 14.5" really scares people. Of course, since I don't have audio, pipes help too. I give tailgaters some leniance, but when I can no longer see their headlight lenses in my rearview, they get to hear my pipes rumble. I give them two warnings, but one is usually enough.
