The MPI Automotive SSMBM812WOM is a 3in over-axle pipe for the GWM Cannon Alpha ute (2.0L turbo petrol hybrid, 2025-on), built without a rear muffler. Leaving the rear muffler out is the defining choice here — it's the freer-flowing, louder-finishing over-axle section.
What does 'over-axle without rear muffler' mean?
The over-axle pipe is the section that arcs up and over the rear axle to reach the tailpipe. This SSMBM812WOM does that span in 3in but deletes the rear muffler from the run — so exhaust isn't quietened at the back, and the ute finishes louder and freer-flowing than a version that carries a rear can. It's the choice for an owner who wants the most open note this section can give. Because there's no muffler in this part, the volume is set higher than the muffled alternative; the rest of the system still does its share of quietening.
Why stainless on the Cannon Alpha?
This is the stainless build of the over-axle section, which is the corrosion-resistant path — it holds up to road salt, moisture and the heat cycling a ute lives with better than a plainer finish over time. On a 2025-on Cannon Alpha that's working or touring, the longer service life is the argument for the stainless version. 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, not a cat-back or cat-delete — it doesn't touch the catalytic converter, so the cat-delete off-road rules don't apply to this part. Running without a rear muffler does raise the finished volume, which can put a vehicle outside noise limits, so confirm the in-service note and any state requirements with the workshop before fitting.
