The aFe BladeRunner exhaust manifold for 2003–2007 Dodge Ram 5.9L Cummins addresses factory manifold cracking with a thick-wall, reinforced flange design cast from 304 stainless steel. Matched ports and a merged-runner layout outflow the factory manifold by roughly 23%, improving exhaust flow, turbo spool and throttle response. The manifold includes two EGT probe ports and a thicker flange for increased strength and reliability.
