STR166 is a performance exhaust muffler for the Holden Commodore from 2007. Supplied by Redback, it's a single silencer with a performance lean — built to flow more freely than a standard restrictive box while still doing real silencing work.
What is a performance muffler?
A performance muffler trades some of the restriction of a stock silencer for better flow, opening the note up a little while keeping the exhaust civil. It's one box, not a full kit — a targeted replacement for the standard muffler. On a 2007-era Commodore it's the part to fit when you want a freer-breathing, slightly fuller note without committing to a whole-system change or running straight through.
How does it sit on a 2007 Commodore?
This muffler is listed for the Holden Commodore from 2007, slotting into the existing run in place of the factory silencer. It mates to your current pipework and hanger points. Because Commodores of that era came in several bodies and exit layouts, confirm your exact model, body and the rest of your exhaust with the workshop so the right muffler and routing are matched.
Will it change the sound much?
A performance muffler lifts the note over stock while still silencing — it's freer-flowing than the restrictive factory box, not a straight-through delete. The result is fuller and a touch louder rather than raucous. We can talk through how it pairs with the rest of your Commodore's exhaust to land the character you're after.
What does fitting involve in the Illawarra?
Oak Flats Muffler Men supplies and fits this performance muffler in-house across the Illawarra. We remove the old silencer, fit the STR166, and check the hangers and alignment so it sits clean. Bring your Commodore in and we'll confirm the fit and book it.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
