The Redback STR131TP is a dual-exit rear muffler delete pipe, listed to fit the 5.7L V8 Holden Commodore VT, VX, VY and VZ sedan. Instead of a rear muffler it runs straight pipe to two tailpipes — the loudest, freest-flowing option at the back of the car.

What does a muffler delete pipe do?

This replaces the rear muffler with straight pipe that exits through two tailpipes. With no rear muffler in the path there's nothing absorbing or reflecting the V8's note at the back, so it's the freest-flowing and loudest rear option for the VT-VZ V8 sedan. It's a deliberately raw choice, not a quietening one.

How loud is it and who suits it?

Deleting the rear muffler lets the 5.7L V8 through unchecked at the tail, so expect a much louder, harder note than any chambered rear. We won't put a decibel figure on it, but this is the option for someone chasing maximum volume and flow off the back of the car — not for those wanting it civil.

Is it road legal?

A rear-muffler delete makes the car significantly louder, and exhaust-noise limits apply to road-registered vehicles in NSW. We won't claim it meets them. Treat this as a part where the noise-compliance question must be settled with the workshop before it goes on a registered car.

What's involved in fitting at Oak Flats?

Oak Flats Muffler Men fits dual-exit delete pipes like the STR131TP in-house across the Illawarra. We check the two tips sit square in the rear valance and the hangers line up on your VT-VZ, then book the bay once it's confirmed for your sedan.

Common questions

Does the STR131TP have a muffler?
No — it's a muffler delete pipe, running straight pipe to two tailpipes in place of the rear muffler, so it's the loudest rear option.
Is it loud?
Yes — deleting the rear muffler makes the V8 much louder. Settle the noise-compliance question with the workshop before fitting it to a registered car.
