The Redback TLX46640-PR is an extreme-duty twin 4in turbo-back exhaust with a resonator, listed to fit the Toyota Landcruiser 79 Series Dual Cab. The twin 4in bore is the standout — this is the big-flow end of the range, with a resonator to tune drone rather than a full muffler.
What does twin 4in turbo-back suit?
Bore is an application choice, and twin 4in is about as large as it gets for a 79 Series — built for a worked, high-output diesel rather than a standard tourer. The TLX46640-PR runs a resonator instead of a chambered muffler: a tuning device that targets drone frequencies while staying free-flowing, so the system keeps the airflow the twin 4in is there to provide.
What does turbo-back cover on the 79 Series?
Turbo-back replaces the exhaust from the turbo outlet back to the tailpipe — a longer span than a cat-back and the section where a turbo-diesel frees up most. In twin 4in this is a substantial extreme-duty system, reflected in the price, aimed at owners building the whole turbo-back in one hit on a 79 Series Dual Cab.
Will it suit my 79 Series Dual Cab?
It's listed to fit the Toyota Landcruiser 79 Series Dual Cab. The 79 Series spans several builds, so send your exact configuration to the workshop and we'll confirm the twin 4in turbo-back suits before ordering.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men supplies and fits the TLX46640-PR in-house across the Illawarra, where we fit plenty of 79 Series systems. A twin 4in turbo-back is a full hoist job — we run both banks from the turbo back, set the resonator and hangers and check clearance under the chassis, tray and any underbody gear.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
Common questions
- Why a resonator instead of a muffler on the TLX46640-PR?
- The resonator targets drone frequencies while staying free-flowing, which keeps the airflow the twin 4in is built for. We describe the design rather than quote a sound level.
- Is it turbo-back or cat-back?
- Turbo-back. It replaces the exhaust from the turbo outlet to the tailpipe in twin 4in, a longer run than a cat-back.
