The Redback K-RPM16066 is a cat-back exhaust listed to fit the Holden Commodore sedan (Series 2). The slug records a 2.5in system with a dual outlet, so it replaces the pipework from the catalytic converter back, supplied by Redback and fitted at our Illawarra workshop.

What does this system cover?

As a cat-back, the K-RPM16066 replaces the exhaust from the catalytic converter rearward, leaving the factory cat and the engine-side hardware in place. The slug records a 2.5in size and a dual outlet at the rear. Redback does not publish the material or muffler detail for this listing, so we confirm those against the part at fitting rather than quoting figures we cannot see.

What is a cat-back and what does it change?

A cat-back covers the section most owners replace first: it swaps the centre and rear pipework and the muffler while keeping the cat and the front pipe standard. On a Commodore sedan it changes the back half of the system and the exhaust note relative to stock, without disturbing the emissions hardware up front. It is a tailpipe-back upgrade rather than an engine-back one, which keeps the install straightforward.

Will it suit my Holden Commodore?

It is listed to fit the Holden Commodore sedan, Series 2. This system matches that body and the 2.5in dual-outlet layout in the listing, but the supplier does not break out engine or sub-variant detail, so confirm your exact build with the workshop before ordering. Fitment feed data can be imperfect.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Redback cat-back systems like the K-RPM16066 in-house across the Illawarra. We check it against your Commodore's hangers and rear layout, fit the dual outlet to sit square, and seal each join. It is listed to fit the Commodore sedan Series 2; send your build and we will confirm it before booking the bay. The recommended retail price is $502.36.
