Twin 4in, muffler gone: the Redback XP00673-40 is an extreme-duty twin 4in muffler delete for the Toyota Landcruiser 79 Series double cab. The 4in twin layout is the headline — large-bore, paired pipework with the muffler removed for a big, open note.
What does the 4in twin muffler delete cover?
This is an extreme-duty part that runs twin 4in pipework and deletes the muffler. A 4in bore is large — sized for a heavily worked or modified driveline rather than a stock engine — and the twin layout doubles the pipework at that point. With the muffler gone there's nothing absorbing or reflecting the pulses there, so the result is loud and open. The 'extreme duty' tag points to the heavier-gauge, hard-use build.
Why a 4in bore on the 79 Series?
At 4in this is a large bore that suits a high-output or heavily modified 79 Series build where flow is the priority. On a double-cab work truck the extreme-duty construction is there to survive corrugations and load, while the big bore plus muffler delete is a deliberate choice for maximum flow and presence rather than restraint.
Is it road legal?
This deletes a muffler rather than the catalytic converter, so it doesn't change the emissions hardware — the supplier doesn't list a cat with it. The note will be substantially louder, and exterior noise has firm legal limits, so confirm your state's noise requirements and the exact build with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this extreme-duty delete in-house across the Illawarra. Twin 4in pipework on a double cab needs careful routing and clearance checks under the tray and chassis, so we confirm the fit on the truck and set the hangers. RRP is $375; bring the 79 Series in and we'll talk through the loud, open note before booking.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
