The MPI Automotive SSMBM812MF is a 3in over-axle pipe for the GWM Cannon Alpha ute (2.0L turbo petrol hybrid, 2025-on), built with a rear muffler. Carrying the rear muffler is what sets it apart — it's the quieter, more civil over-axle option of the pair.
What does the rear muffler add over the WOM version?
The over-axle pipe arcs up and over the rear axle to reach the tailpipe. This SSMBM812MF runs that 3in span and includes a rear muffler, so the note is quietened at the back before it exits — a more subdued, cabin-friendly finish than an over-axle section that deletes the muffler. A chambered muffler absorbs and reflects to soften overall volume, so for a Cannon Alpha owner who wants the upgrade without the loudest possible note, this is the muffled choice. The rest of the system still contributes; this part adds the rear quietening stage.
Why stainless for a working ute?
This is the stainless build of the section, the corrosion-resistant path that stands up to moisture, road salt and heat cycling better over a ute's working life than a plainer finish. On a 2025-on Cannon Alpha hybrid that does real kilometres, that longevity is the case for stainless. It's listed to fit the GWM Cannon Alpha 2.0L turbo petrol hybrid ute from 2025; confirm your exact build with the workshop.
Is it road legal?
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, so confirm the in-service note and any state requirements with the workshop before fitting.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits Cannon Alpha over-axle sections in-house across the Illawarra, checking the pipe and rear muffler clear the axle through its travel and mate to the rest of the system. The SSMBM812MF carries a published RRP of $712.80; send your build and we'll confirm fitment and book the bay.
