This is a complete engine-back system, not a section: the Exhaust Systems Australia TOYOTA-LANDCRUISER-HZJ75-HZJ78-4-2L-DIESEL-2-1-2-INCH-COMPLETE-STAINLESS-SPORTS- is a 2½in 304-stainless exhaust with muffler, listed to fit the HZJ75/HZJ78 Landcruiser 4.2L diesel and running the full length from the engine back.

What does "engine-back" cover here?

An engine-back system replaces the exhaust from the engine all the way to the tail — the longest replacement span, the full run rather than a mid or rear section. On a naturally aspirated 4.2L diesel HZJ75/78, going to a 2½in stainless engine-back in one piece means matched pipework the whole way and a single new muffler, instead of patching old factory sections together. It's the complete renewal for a hard-worked Cruiser.

Why 304 stainless and 2½in?

These troop-carrier and cab-chassis 70 Series Cruisers are working and touring vehicles that live in salt, dust and water crossings, so corrosion resistance matters. The 304-stainless build resists rust and heat-bluing far better than mild steel over a long life. The 2½in bore suits the 4.2L diesel's flow, and the single muffler keeps the note manageable on a system that runs the full length of the truck.

Is it road legal?

Whether this system retains the factory emissions hardware isn't published by the supplier, so we don't claim it does or doesn't. Confirm the exact build and any NSW registration requirements with the workshop before fitting, especially as emissions rules vary for diesel 4x4s.
