Built for the V8, the Redback STR131 is a rear muffler with twin tail pipes listed to fit the 5.7L Holden Commodore VT and VX. The twin outlets give the back of these V8 sedans the look to match the engine, while the box handles the silencing.
What does the twin tail pipe add?
Twin tail pipes mean the rear muffler exits through two outlets at the rear valance rather than one — a fuller, more deliberate finish that suits a V8 car. The muffler body still does the silencing job; the dual exit is the presentation and packaging detail. On the 5.7L VT/VX it is the rear box that sets most of the note while finishing through the twin tips.
Why the 5.7L V8 fitment matters
This is listed specifically for the 5.7L V8 VT and VX. Holden packaged the V8 cars differently to the sixes, with their own rear routing and clearances, so a box cut for the 5.7L is the one that lines up under a V8 Commodore. Matching the engine is what keeps the twin-tip rear sitting correctly at the valance.
Will it suit my VT or VX Commodore?
It is listed to fit the 5.7L Holden Commodore VT and VX. Confirm your exact series and body with the workshop before ordering, since the listing is a guide and the V8 rear routing can vary across these cars. Send the details and we will match the box to your car.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits twin-tip rear mufflers like the STR131 in-house across the Illawarra. We line the two tips up evenly at the valance, check the feed pipe and hangers, and make sure the box clears the rear suspension before handing the car back.

Common questions
- Is the STR131 for the V8 Commodore?
- Yes — it is listed for the 5.7L V8 Holden Commodore VT and VX as a twin-tailpipe rear muffler. Confirm your exact series with the workshop first.
- Do the twin tips make it much louder?
- The dual outlets are mainly a look-and-packaging detail; the muffler body still does the silencing. Expect a tidy V8 finish rather than a big volume jump from the tips alone.
