The Redback STR121 is a centre exhaust section with an integrated muffler, listed to fit the Holden Commodore. Supplied as a mid pipe-and-silencer unit, it replaces the underfloor run between the front of the system and the rear box rather than a bare muffler alone.
What does a centre exhaust section include?
This is the mid-section delivered as a pipe-and-muffler assembly: the centre run with its silencer built in, ready to join at the front and rear rather than a standalone box you splice into old pipe. On the Commodore it carries the first stage of quietening along the floor and sets a known length for the mid run, which means cleaner joints than patching a single box into tired pipe.
When is a section better than a single box?
If the centre pipe is as rusted as the muffler, replacing the whole mid section in one piece is tidier and longer-lived than welding a new box into old tube. The STR121 covers that mid run as an assembly, so the joints land at fresh pipe ends. It is a silencing-and-routing replacement, not a tone change.
Will it suit my Commodore?
It is listed to fit the Holden Commodore. Commodore spans many series and bodies, so confirming your exact build is essential before ordering — feed data is a guide and the centre routing varies across the range. Send the details and Oak Flats Muffler Men will match the section to your car.
What does fitting involve in the Illawarra?
We fit centre exhaust sections like the STR121 in-house across the Illawarra. We get the car up, cut back to sound pipe if needed, fit the section to the hangers, and make sure the muffler clears the floor and driveline before the car goes back.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
