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


A compact straight-through resonator for the centre of the system, the MPI Automotive MBM774PHD is the 3in centre hotdog for the GWM Cannon ute (2.0L turbo-diesel, 2020–2024). It targets cruise drone without packing the pipe, so it sits between an open centre and a full muffler.
A hotdog is a small resonator with a straight-through core — gas passes the centre without the chambering of a conventional muffler. Its job is to knock down the resonant frequency that shows up as drone at steady throttle, while keeping flow close to an open pipe. On the Cannon's 2.0L diesel at 3in, it suits the owner who wants a freer-breathing centre and a fuller note but not the constant cruise drone of running the centre bare.
It's listed to fit the GWM Cannon ute 2.0L turbo-diesel from 2020–2024. Running changes apply across that window, so send your exact build and we'll confirm the hotdog routing and clearances match before anything is ordered.
The hotdog replaces the factory centre silencer and leaves the catalytic converter and DPF ahead of it in place. Noise regulations still apply to any exhaust change, so confirm the road-legal build and any state requirements with the workshop before fitting.
Oak Flats Muffler Men fits Cannon centre resonators in-house across the Illawarra. MPI Automotive supplies the hotdog; we check hangers and tunnel clearance, then book the bay once the fitment is confirmed. The RRP on this listing is AUD 385.
