Toyota Landcruiser HZJ75, HZJ78 1HZ Outside Chassis ## Mandrel Bent ## for Extractors - Toyota.
Category: Extractors and headers
The Exhaust Systems Australia TOYOTA-LANDCRUISER-HZJ75-HZJ78-1HZ-OUTSIDE-CHASSIS-MANDREL-BENT is an outside-chassis, mandrel-bent extractor set listed to fit the Toyota Landcruiser HZJ75 and HZJ78 with the 1HZ engine.
Extractors replace the cast factory exhaust manifold with individual tubular runners that merge into a collector. "Outside chassis" describes how the runners are routed — taken out and around the chassis rail rather than tucked tight inside it, which is a common approach on a tall diesel six like the 1HZ where header room is limited. Mandrel bending keeps the tube bore constant through each bend, so the exhaust gas keeps a smoother path than it would through a crushed cast manifold.
It's listed to fit both the HZJ75 and HZJ78 Landcruiser with the 1HZ engine — closely related chassis from the 70 Series family. They share a lot, but accessory routing, turbo fitment and chassis hardware vary between builds, so confirm your exact vehicle with the workshop before ordering. The supplier doesn't publish a separate gasket part number in this listing, so we'll confirm what your fit needs at the bench.
Whether an extractor change stays compliant depends on the rest of the exhaust and on NSW rules, and this listing publishes no rating either way. We won't claim one for you. Bring the vehicle in and we'll work through what the build needs before any work starts.
Oak Flats Muffler Men fits 1HZ extractor sets like this in-house across the Illawarra. The old manifold comes off, the outside-chassis runners go on, and clearance is checked against the chassis rail and surrounding hardware. The recommended retail is $885. Send your exact HZJ75 or HZJ78 details and we'll confirm clearances, gaskets and book the bay.
