K-RPM16023 is a dual 3in cat-back exhaust with a rear muffler for the Holden Commodore. Supplied by Redback, a cat-back replaces everything from the catalytic converter back — here as a full twin 3in run finishing in a rear silencer.
What does a cat-back system cover?
Cat-back means the exhaust is replaced from the catalytic converter rearward, leaving the converter and the emissions hardware ahead of it in place. This one is a dual 3in layout, so both banks run their own 3in pipe back to a rear muffler that keeps the exit note controlled. It's a complete back half of the exhaust rather than a single section — the common upgrade path because it frees up the run while keeping the factory cat.
Why the dual 3in bore?
At 3in per bank this is the larger pipe size, sized for a bigger or modified Commodore rather than stock pipework, with the dual layout giving each side its own path back. The rear muffler keeps the note in check at the tailpipe rather than running straight through. It's listed to fit the Holden Commodore; confirm your exact model, engine and any prior work with the workshop, as a full cat-back is a significant fit.
Is it road legal?
Because a cat-back keeps the catalytic converter, this kit leaves the emissions equipment ahead of it in place — the key point for road compliance. Final noise still depends on the whole build, so confirm the finished system suits your registration and use. The workshop will go through this with you before fitting.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men supplies and fits cat-back systems like this in-house across the Illawarra. A full dual 3in run takes proper bench time — we fit both banks, set the rear muffler, and check clearances and hangers along the length. Bring your Commodore in and we'll confirm the build and book the bay.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
