GWM Cannon Ute, 2.0L TD, 2020-2024, 3in Centre Muffler for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive SSMBM774MF is a 3in centre muffler for the GWM Cannon ute (2.0L turbo-diesel, 2020–2024). As the chambered centre option, it's the quietest, most composed of the 774 centre choices — built to settle the note rather than open it up.
A muffler quietens by absorption and reflection inside its chambers, so the centre version of the 774 is the one that keeps things civil. On the Cannon's 2.0L diesel at 3in, it replaces the factory centre silencer with a unit that flows better than stock while still tempering the note. It's the pick for owners who want the breathing improvement of a fresh 3in centre without the extra volume that comes from running a hotdog or open pipe.
It's listed to fit the GWM Cannon ute 2.0L turbo-diesel from 2020–2024. There were running changes across that span, so send your exact build and we'll confirm the centre-muffler routing and clearances match before anything is ordered.
This centre muffler swaps the factory silencer and leaves the catalytic converter and DPF ahead of it untouched. Exhaust noise rules still apply, so confirm the road-legal build and any state requirements with the workshop before fitting.
Oak Flats Muffler Men fits Cannon centre mufflers in-house across the Illawarra. MPI Automotive supplies the muffler; we check hangers and centre-tunnel clearance, then book the bay once the fitment is confirmed. The RRP on this listing is AUD 752.40.
