Redback Standard Centre Muffler.8L (M4938) Fits
Category: Mufflers and resonators


The Redback M4938 is a standard centre muffler listed to fit the Holden Commodore VS series wagon and ute with the 3.8L six-cylinder. Its defining role is the position and the brief: a standard-style centre silencer, not a louder performance can.
The centre muffler sits in the middle of the exhaust run, ahead of the rear section, and does much of the quietening before the gas reaches the back of the car. As a standard-style chambered muffler the M4938 keeps the note close to how Holden intended rather than opening it up — useful when the original centre silencer has rusted through and you want a like-for-like replacement. No bore or material is published, so we won't quote either.
It's listed to fit the VS-series Commodore wagon and ute with the 3.8L six. That engine and body combination set the muffler's length and connection points, so it's a body-and-engine-specific part rather than a universal silencer. Confirm your exact VS and that it's the 3.8L six with the workshop before ordering.
As a centre muffler it replaces the existing centre silencer only, leaving the catalytic converter and rear section in place. It's the quiet, standard-style option — ideal when you want the VS back to a stock-like note rather than a performance change.
Oak Flats Muffler Men supplies and fits the M4938 in-house across the Illawarra. We check the centre muffler's inlet and outlet against your Commodore's pipework, confirm the hanger positions for the wagon or ute floor, and fit it in. Tell us your VS and we'll confirm the fit.
