GWM Cannon Alpha Ute, 2.0L Turbo Petrol Hybrid, 2025 On, 3in Over Axle With Rear Muffler (SKU: MBM812MF) Engineered.
Category: Mufflers and resonators


The MPI Automotive MBM812MF is a 3in over-axle pipe for the GWM Cannon Alpha ute (2.0L turbo petrol hybrid, 2025-on), built with a rear muffler. It's the muffled over-axle section at a value price — quieter at the back than a no-muffler run, without a premium-finish premium.
The over-axle pipe arcs up and over the rear axle to reach the tailpipe, and this MBM812MF carries a rear muffler in that 3in span. A chambered/absorptive muffler softens the note at the back before it exits, so the ute finishes more subdued and cabin-friendly than a section that deletes the muffler. For a Cannon Alpha owner who wants the upgrade with the quieter finish but at a keen price, this is the muffled, value-finish choice. The rest of the system still contributes; this part adds the rear quietening stage.
At a published RRP of $445.50, the MBM812MF is the value-finish over-axle option that still includes a rear muffler — a step up in quietening from the no-muffler section, without paying for a premium finish. It's the middle-ground pick of the Cannon Alpha over-axle range. It's listed to fit the GWM Cannon Alpha 2.0L turbo petrol hybrid ute from 2025; confirm your exact build with the workshop.
This is an over-axle pipe with a rear muffler — it doesn't touch the catalytic converter, so the cat-delete off-road rules don't apply to this part. Noise outcomes still depend on the full system; confirm the in-service note and any state requirements with the workshop before fitting.
