PPE Engineering Headers Infiniti M56 | M56x 2010-2019(155601-SS) PPE_CeramicCoating_3 BM9-HDR4 kit features ACT's mostWe have tremendous respect for builders of all types out there. Nothing is harder to piece together than a good set of exhaust headers and the guys at PPE know what they are doing. Mandrel bent, and boasting a black ceramic coating or a polished ceramic coating, these headers will help unlock that last bit of juice that you could not get with an exhaust upgrade alone. PPE Headers have a significant increase in flow compared to the stock manifolds.
