They are equal length pipes, keeps the exhaust flow tuned properly (so that the exhaust released from each cylinder are kept in order and not bunched up where they will restrict each others flow through the downpipe/collector/cat/exhaust... Don't know if that makes sense, but if each exhaust burst has to travel different distances (like on normal headers), then when they go into the downpipe, some of them get bunched up (one travelling a longer distance might come into the downpipe at the same time as one that travels a shorter distance)....
