The MPI Automotive FX-557 is a V8 extractor set listed to fit the Nissan Patrol GQ and GU with an LS engine conversion — the LS1, LS2 and LS3 Gen III V8s (5.7L and 6.2L) on a Marks conversion using the Marks adaptor kit. It replaces the swap-engine manifolds with tube-style headers built for that conversion.

What does this extractor set cover?

This is a header set for the GQ and GU Patrol that has been converted to an LS V8. The listing names the LS1, LS2 and LS3 Gen III engines in 5.7L and 6.2L capacities, fitted via a Marks conversion with the Marks adaptor kit. As a V8, it covers both cylinder banks, and because an LS swap doesn't have a factory exhaust path in the Patrol, an extractor set designed around that conversion is what makes the engine and the chassis work together at the front of the system.

What's an extractor and why does the conversion need one?

An extractor bolts to the cylinder head and merges each cylinder's exhaust through tubes of more even length than a cast manifold. On a factory vehicle it's an upgrade; on an engine conversion it's often a necessity, because the donor V8 has to clear the Patrol's steering and chassis rails. This set is built around the Marks adaptor kit geometry, which is why the listing is specific about the conversion hardware rather than treating it as a generic LS header.

Will it suit my LS-converted Patrol?

The FX-557 is listed to fit GQ and GU Patrols running an LS1, LS2 or LS3 on a Marks conversion with the Marks adaptor kit. Conversions vary in detail, so confirm your exact engine, body and conversion hardware with the workshop before ordering — this set is matched to the Marks setup specifically.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits conversion extractors in-house across the Illawarra. An LS-swap V8 header job means working both banks in the converted engine bay, checking clearances around the steering and chassis, and tying into the system. The FX-557 is supplied by MPI Automotive at an RRP of $1,092.08; contact us to confirm your conversion details and book the bay.
