What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this Commodore cat-back in-house across the Illawarra. We start from the listed fitment, put the car on the hoist, check the rear pipework clears the underbody and the hangers sit right, then book the bay. The $144.99 part reaches us through SWD as the supplier, so we confirm availability and the exact fit before it's ordered.

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

A cat-back is everything behind the catalytic converter — the mid and rear pipework, muffler and tailpipe. Swap it and you change the back-half flow and the note while the converter and front pipe stay standard. On a Commodore that makes it a contained rear-section job, not an engine-back rebuild. Louder than stock is the usual outcome; no sound figure is published, so we leave it at that.

Will it suit my Holden Commodore?

This STR179 listing names the Holden Commodore from 2007, with no series or engine recorded for the part. Feed data can be imperfect, so treat it as listed to fit rather than confirmed for every build — give us your exact Commodore, body and year, and we'll check it against the part first.

Is it road legal?

As a cat-back it keeps the factory catalytic converter, which is the piece that matters for road use. We don't hold published compliance figures for this kit, so we'll walk through how it sits on your Commodore and any state requirements rather than make a claim we can't back.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
