Cummins 6B 5.9L Exhaust Manifold, New (4020065)

Are you willing to leave MPG on the table?

The Exhaust Manifold never gets the credit it deserves… that is, until it forms a crack. While it doesn’t look like the Exhaust Manifold is an integral part of your engine, that leaking exhaust gas is just horsepower, torque, and ultimately, fuel efficiency vanishing into thin air.

Whether you are seeking a replacement Exhaust Manifold, increased fuel efficiency, or are looking for a extra “kick” on the highway with a Performance Exhaust Manifold, 4BTdiesel has you covered. And, while some equate aftermarket parts with the term, “subpar”, 4BTdiesel is here to set the record straight. 4BTdiesel only offers premium Exhaust Manifolds with a industry leading 6-month warranty, all with savings up to 50% off OEM prices.  How’s that for an aftermarket part?
