Nissan Navara 4WD Z24 2.4L 4cyl Petrol Extractor.
Category: Extractors and headers


The MPI Automotive FX-511 is a set of replacement extractors listed to fit the Nissan Navara 4WD with the Z24 2.4L four-cylinder petrol engine. Extractors swap in for the factory cast manifold, so this is a front-of-system part rather than a tailpipe change.
The FX-511 is the extractor stage for the Z24-powered Navara — tubular headers that bolt to the cylinder head in place of the original cast manifold. They cover the run from the head flange to where the rest of the exhaust picks up, and nothing further back. Any pipework, catalytic converter or mufflers behind them are separate parts; this listing is the headers on their own.
Extractors are tubular headers that give each cylinder its own primary pipe before the pipes merge, rather than the short shared passages of a cast manifold. On an older petrol four like the Z24 the aim is to let the engine breathe out more freely. The honest trade-offs: tubular headers usually change the exhaust note, they sit in a tighter space so clearance matters, and the original heat shielding or sensor bungs sometimes need carrying across. We publish no power or sound figures for the FX-511 — those depend on the rest of your system and tune.
The FX-511 is listed to fit the 4WD Nissan Navara with the Z24 2.4L petrol engine; treat that as a starting point, not a guarantee, because catalogue feed data can be imperfect. Note the 4WD distinction — there is a separate listing for the two-wheel-drive cars — so confirm your exact build with the workshop before ordering.
Oak Flats Muffler Men supplies and fits extractors like the FX-511 in-house across the Illawarra. It is head-end labour: freeing the existing manifold, transferring sensors and shields, and checking clearance and gasket seal before the rest of the system goes back on. It carries a recommended retail price of $559.05, supplied by MPI Automotive; if it is not on the shelf we order it in.
