They are part of the EGR system, its out dated Japanese technology to reduce what comes out the exhaust. Its better to remove EGR, but doesn't hurt to keep it there. The hoses were removed to stop it from working probably, they used to attach to the maze of vacuum hoses at the cluster. Its ok to not have it working, not a requirement of wof or anything.
