The Redback K-RPM15713 is a dual 2.5in cat-back exhaust listed to fit the Holden Commodore V8 across the VT, VX, VY and VZ. It runs twin rear pipes and changes the section behind the catalytic converter, and it's sold and fitted at our Illawarra workshop.

What does this system cover?

This is a dual 2.5in cat-back for the Commodore V8 across the VT, VX, VY and VZ. A cat-back replaces the exhaust from the catalytic converter back to the tips, so the factory cat and front pipework stay in place and only the rear section changes. The listing describes a dual 2.5in layout. Material and muffler details aren't published for this part, so we don't quote them — they're confirmed against the kit at fitting.

What does a dual 2.5in cat-back change?

A cat-back is the section behind the catalytic converter, so swapping it changes the rear flow and the note without touching the emissions hardware up front. A dual 2.5in layout gives the V8 two rear paths rather than one, suited to the Commodore V8 it's listed for. The change sits behind the cat across the VT–VZ range, and the note will be louder than the factory system.

Will it suit my Holden Commodore?

It's listed to fit the Holden Commodore V8 in the VT, VX, VY and VZ. The record names Holden, the Commodore model and the V8 engine, with those series in the listing. Fitment feed data can be imperfect, so confirm your exact series with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits dual cat-back systems like the K-RPM15713 in-house across the Illawarra. We check the listed fitment against your Commodore, confirm which series you have and that the twin 2.5in pipework clears the underbody, and book the bay. The recommended retail price is $720.55. Send your Commodore details and we'll confirm the build first.

Common questions

Which Commodores does the K-RPM15713 fit?
It's listed for the V8 across the VT, VX, VY and VZ. Confirm your exact series with the workshop before ordering.
Is it a single or dual system?
It's a dual 2.5in cat-back, so it runs two 2.5in rear pipes.
Does it keep the catalytic converter?
Yes — it's a cat-back, so it changes the section behind the catalytic converter and leaves the factory cat in place.
