Redback Performance 2.5" Exhaust System.
Category: Complete exhaust systems

The Redback K-RPM15720 is a 2.5in cat-back system listed for the Holden Commodore in VN, VP and VR guise, priced at $354.48 AUD. The 2.5in figure comes straight from the listing; it covers the run behind the catalytic converter.
This is a 2.5in cat-back, so the 2.5in bore applies to the section it replaces — everything from the catalytic converter rearward on the Holden Commodore VN, VP and VR. The front pipe and cat are left factory. Redback does not publish a material on this SKU, so we confirm that detail against the part rather than state it here.
The K-RPM15720 is set up for the VN, VP and VR Commodore — the early-1990s wave of the Holden sedan and wagon. Those three series share enough underneath that a single listing spans them, but trim and driveline still varied, so the listing is a fitment guide, not a guarantee for your individual car.
On a car like the VN-to-VR Commodore, a cat-back is the rear-section swap: it leaves the catalytic converter and front plumbing as Holden built them and changes only the piping behind. It is the least disruptive of the exhaust options, which is why it is a common first upgrade. The character of the note shifts with that rear run and its muffling — we do not attach a sound figure, because the supplier publishes none.
We supply and fit the K-RPM15720 in-house across the Illawarra. The 2.5in kit goes up on the hoist, we check it clears the underbody and the hangers seat properly, then book it in. Send your VN, VP or VR details and we will confirm the match first.
