This Exhaust Systems Australia 2-1/2in header, connecting pipe and muffler kit is listed to fit the Toyota LandCruiser HZJ79 cab chassis and pick-up with the 4.2L 1HZ diesel built from 10/99 to 8/2007. Sized at 2in, it covers the front and middle of the system on the 79-series Cruiser.
What does this kit cover?
This bundles the headers that replace the manifold, a connecting pipe to carry the gas back, and a muffler to keep the note in check, so it is the front and middle of the exhaust as a matched package rather than separate parts. The 2in figure describes the pipework. With the muffler included, the system finishes quietly rather than open on the 1HZ diesel.
What is a header-and-muffler kit on a diesel?
Headers give each cylinder its own runner off the head, and on a turbo-less 1HZ diesel this kit pairs that with the connecting pipe and muffler for a complete front-to-mid section. A muffler keeps the exhaust civil rather than raucous. This is the later HZJ79 version of the 70-series kit, scoped to the 10/99-to-8/2007 build window. No power or sound figures are published by the supplier.
Will it suit my LandCruiser?
It is listed for the HZJ79 cab chassis and pick-up with the 4.2L 1HZ diesel from 10/99 to 8/2007. Earlier 70-series Cruisers take a different kit, so confirm your exact model and build date with the workshop before ordering rather than going by the badge.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits header-and-muffler kits like this in-house across the Illawarra.

Supplied by Exhaust Systems Australia at $1,280 AUD; tell us your HZJ79 build date and we will confirm the kit before booking the bay.
