The Exhaust Systems Australia TOYOTA-LANDCRUISER-HZJ80-1HZ-4-2L-OUTSIDE-CHASSIS-MANDREL-BENT-USE-DSF082-X-2-GA is an outside-chassis, mandrel-bent extractor set listed to fit the Toyota Landcruiser HZJ80 with the 1HZ 4.2L. It pairs with the DSF082 gasket (x2) and is the manifold-out upgrade rather than a tailpipe change.
What are outside-chassis mandrel-bent extractors?
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.
Will it suit my Landcruiser HZJ80?
It's listed to fit the HZJ80 Landcruiser with the 1HZ 4.2L diesel six. That's a specific chassis and engine, but accessory routing, turbo fitment and chassis hardware vary between builds, so confirm your exact vehicle with the workshop before ordering. The listing also calls for the matching DSF082 gasket, supplied as two (x2), which is fitted with the extractors.
Is it road legal?
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.
What does fitting involve at our Illawarra workshop?
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 with fresh DSF082 gaskets, and clearance is checked against the chassis rail and surrounding hardware. The recommended retail is $1,335. Send your exact HZJ80 details and we'll confirm clearances and book the bay.
