The SSMBM445MF is a 2in dual rear muffler for the Holden VY/VZ V8 Adventra — sized to the bore the all-wheel-drive Adventra wagon ran rather than a larger performance-sedan system.

Why the 2in bore on the Adventra?

The Adventra was Holden's all-wheel-drive VY/VZ wagon, and its rear runs a 2in section. A 2in bore matches the Adventra's standard-flow V8 setup, keeping gas speed up through the wagon's rear rather than oversizing the pipe for an engine that wasn't built to chase the larger-bore route.

What does the dual rear cover?

This is a dual rear muffler section feeding both tailpipes at the back of the Adventra wagon. Sitting at the rear of the system, it does the final silencing on the AWD wagon while the 2in bore suits its standard exhaust sizing.

Will it suit my Adventra?

It's listed to fit the Holden VY and VZ V8 Adventra. The AWD wagon's rear floor and driveline differ from the rear-drive Commodores, so this section is specific to it and won't interchange with the sedan or rear-drive wagon parts. Confirm your exact model and rear layout with the workshop before ordering.

What's the fitting process at Oak Flats?

Oak Flats Muffler Men supplies and fits the MPI Automotive SSMBM445MF in-house across the Illawarra. We hoist the wagon, line the rear up with the hangers and tailpipe exits around the AWD driveline, check clearance over the rear floor, and confirm even sit before welding or clamping. Routing a rear around the all-wheel-drive gear takes a careful mock-up, which is part of the in-house fit. Send your model and we'll confirm fit.

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

Common questions

Why is the SSMBM445MF a 2in bore?
The Adventra ran a 2in rear rather than the larger bore on the performance sedans. The 2in bore matches its standard V8 exhaust sizing.
Does it fit a rear-drive Commodore?
No — it's specific to the AWD VY/VZ Adventra wagon, whose rear differs from the rear-drive cars. Confirm your model with the workshop.
