GSR header is taller, because the oil pan is deeper. But I don't know whether the extra height is in the 4-2 section or the 2-1 section.
Also, depending on what year, the GSR 2-1 section is shorter because the cat starts farther forward. The GSR O2 sensor is located in the cat's inlet so the pipe doesn't have a bung.
