The Redback STR131TP is a dual-exit rear muffler-delete pipe listed to fit the 5.7L Holden Commodore. Instead of a silencer, it is a straight pipe with twin outlets that takes the place of the rear muffler — the loudest, most open path at the back of the system.
What is a muffler-delete pipe?
A muffler-delete pipe replaces the rear muffler with plain pipe rather than a silencer, so there is no chambered box at the back to quieten the gas. With its dual exit it finishes through twin outlets at the valance. Removing the rear silencer makes the system markedly louder and more open — this is a sound-and-flow part, not a quietening one, and it suits an owner chasing the rawest rear note from the 5.7L.
How loud is it, honestly?
Because it deletes the rear muffler entirely, expect a much louder, harder note than any replacement muffler — there is nothing at the rear absorbing or reflecting the pulses. Scope this as a loud, open setup rather than a refined one; it is the choice when volume is the point. We will talk through that with you so there are no surprises after fitting.
Will it suit my 5.7L Commodore?
It is listed to fit the 5.7L Holden Commodore. The V8 rear routing varies across the series these cars cover, so confirm your exact model and build with the workshop before ordering. This is a muffler-section delete only — it does not touch the catalytic converter or front-of-system emissions hardware.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits dual-exit delete pipes like the STR131TP in-house across the Illawarra. We line the twin outlets up at the valance, check the feed pipe and hangers, and make sure the pipe clears the rear suspension before handing the car back. Confirm any state requirements with us when you book.

Common questions
- Does the STR131TP make the car much louder?
- Yes — it deletes the rear muffler and runs a twin-outlet straight pipe instead, so it is significantly louder and more open than any replacement muffler. It is a volume part.
- Does it affect the catalytic converter?
- No — it is a rear muffler-section delete only and does not touch the catalytic converter or front emissions hardware. Confirm any state requirements with the workshop when you book.
