Landcruiser HZJ80 4.2L 1HZ Direct Fit Base Only With Flex, Suits FX-700 Tops Only.
Category: Extractors and headers


The MPI Automotive FX-684DFBASE is a direct-fit extractor base section, built with a flex joint and listed to fit the Toyota Landcruiser HZJ80 4.2L 1HZ. It is the base only and is listed to suit the FX-700 tops, so it's part of a two-piece set rather than a standalone extractor.
This part is the lower section of a two-piece extractor arrangement. The record describes it as the base only, designed to suit the FX-700 tops — meaning the upper header tubes are a separate component and this piece completes the run below them. It's a direct-fit design, so it's built to bolt into the factory location on the HZJ80, and it includes a flex joint: a flexible section that absorbs engine movement and thermal expansion to protect the pipework. Because it's a base rather than a complete extractor, the headline thing to get right is pairing it with the correct tops. No sound or performance figures are published with it.
It's listed to fit the Toyota Landcruiser HZJ80 with the 4.2L 1HZ engine, and to suit the FX-700 tops. The HZJ80 chassis code and the 1HZ diesel engine are the qualifiers, and you'll also need the matching tops for a complete fit. Confirm both the engine and the top section you're pairing it with at the workshop before ordering.
This is exhaust hardware that replaces part of the manifold-back run; it doesn't include or remove a catalytic converter on its own, so compliance depends on the complete exhaust once the base and tops are joined. We don't make blanket legality claims — confirm how your full system sits with the workshop before fitting.
Oak Flats Muffler Men fits two-piece extractor sets like the FX-684DFBASE across the Illawarra. We confirm the base pairs with the right FX-700 tops, check clearances on the HZJ80, fit fresh gaskets, and let the flex joint take up engine movement before joining into your pipework. Bring the Cruiser in and we'll verify the 1HZ fitment and the top match before booking.
