The EGR pipe transports exhaust gasses from one of the exhaust manifolds (the pass. side one I believe) to the rear of the intake manifold. It's part of your EGR system, which also includes the EGR valve and modulator, either electrically or vacuum modulated. If the EGR pipe is broken, it can result in a ticking noise, similar to that of when your shims are out of adjustment.
