Exhaust Gas Recirculation. One of the emission control techniques, in which gases are sucked from the exhaust pipes (before the muffler) and re-circulated through the intake manifold (to be 'burned' again). the high heat associated with exhaust gases required expensive metals ... so replacing/repairing this system can be costly.
