The Redback RBH722 is a header set listed to fit the Toyota Landcruiser with the 1HZ 4.2 engine, in the HZJ70, HZJ75 and HZJ78 series. It replaces the factory manifold with a tubular header — the front of an exhaust build on these workhorse 70-Series Cruisers.
What is a header and where does it sit?
A header, or extractor, is the tubular manifold that bolts to the cylinder head and gathers exhaust from each port into separate runners before they merge. It replaces the cast factory manifold and sits right at the front of the exhaust, ahead of anything downstream. The idea is smoother, more even gas flow off the head than a cast manifold allows. On a 1HZ-powered 70-Series Landcruiser — a diesel built for hard work — headers are the foundational piece of an exhaust upgrade, with everything else feeding off them. The RBH722 is supplied set up to suit this engine and chassis rather than as raw tube.
Will it suit my Toyota Landcruiser?
The RBH722 is listed to fit the Landcruiser with the 1HZ 4.2 engine in the HZJ70, HZJ75 and HZJ78 series. Header fitment is tied closely to the engine and chassis, so the listing is a guide rather than a guarantee — confirm your exact series and engine with us. Send your build and we'll check the RBH722 suits your Cruiser before it's ordered in.
Is it road legal?
Whether a header is acceptable on a road-registered Cruiser depends on how it pairs with the emissions hardware downstream and your state's requirements. We won't make an approval claim here — bring the vehicle in and we'll talk through how the RBH722 works with the rest of your system.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits headers like this on the hoist. Swapping a manifold on a 4.2 diesel means clearance, gasket and fastener work against the head, so it's done carefully. At $1509 RRP the set is quoted and ordered against your specific Landcruiser.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Which Landcruisers does the RBH722 fit?
- It's listed for the 1HZ 4.2 Landcruiser in the HZJ70, HZJ75 and HZJ78 series. Confirm your exact series and engine with the workshop, as header fitment is variant-specific.
- Is this a full exhaust system?
- No. It's the header set — the front section that replaces the factory manifold. Anything downstream runs off it.
