The Redback M6178 is a standard rear muffler listed to fit the VN–VP Holden Commodore 3.8L. As the rear unit, it's the silencer at the back of the system that sets the tailpipe note — not the centre piece.
What does the rear muffler do?
The rear muffler is the last silencer in the system and the one that does the most to set how the Commodore sounds at the tailpipe. On the 3.8L VN–VP it carries the final quietening after the centre section. M6178 is the standard, factory-style unit for that rear position, so it returns a tired or blown rear to its original quiet note rather than changing the car's character.
When do you fit just the rear unit?
If your VN–VP's centre section is sound but the rear muffler has rusted through, M6178 is the targeted replacement — renew the rear and keep the rest. It's the common workshop fix for an ageing 3.8L Commodore where the back silencer has given out. Bore and material aren't published for this listing, so the workshop confirms the connections.
Will it suit my Commodore?
It's listed to fit the Holden Commodore VN–VP 3.8L. Send your model and build to the workshop and we'll confirm M6178 is the right rear unit for your car before ordering. RRP is $229.99.
