Sorry replying a month later. I don't frequent this thread. The bar is part of the EGR, exhaust gas recirculation, system. It takes exhaust gas and pumps it into the intake to lower emissions. Huge power robber. A header blocks this flow path so the entire EGR system can be removed. You'll need a tune to disable the CEL this causes.
