318ci V8 500/600/700 series Dodge Truck D3F & D5N Extractor (SKU: FX-781) Engineered. Quality guaranteed.
Category: Extractors and headers


The MPI Automotive FX-781 is a V8 extractor set listed to fit the Dodge 500, 600 and 700 series trucks (D3F and D5N) with the 318ci V8. It replaces the cast factory exhaust manifolds at the heads.
An extractor, or header, takes the place of the cast factory manifold with tuned-length tubes that merge downstream, aiming to reduce back-pressure off the heads. On the 318ci V8 in these Dodge trucks that's a set per bank at the very front of the exhaust. We can't publish power or sound figures for the FX-781 — the supplier doesn't, and we don't invent them.
The FX-781 is listed to fit the 318ci V8 across the Dodge 500, 600 and 700 series (D3F and D5N). The supplier hasn't published exact build years, so confirm your series, engine and chassis code with the workshop before ordering. We treat it as 'listed to fit' rather than guaranteed, since feed data on commercial trucks this age can be incomplete.
Oak Flats Muffler Men fits truck V8 extractors in-house. On these older Dodge trucks we check head-face condition, stud access and how the extractors mate to the existing system before committing. Send your truck's details and we'll confirm the FX-781 and book the work.
The FX-781 is an MPI Automotive part with a recommended retail of $932.99. As a header for an older commercial V8 it may need to be ordered in, so ask us about lead time when you book.
