GWM Cannon Ute 2.0L TD 2020 - 2025, 3in Turbo Back With Hotdog, Without Cat (SKU: SSMKGW0009) Engineered for
Category: Mufflers and resonators


The MPI Automotive SSMKGW0009 pairs a straight-through centre hotdog with a catalytic-converter delete on its 3in turbo-back for the 2.0L TD GWM Cannon ute (2020–2025) — open flow with just enough resonator to take the hardest edge off, and an off-road system.
A hotdog is a compact straight-through resonator — packed tube, not a baffled box — so on the SSMKGW0009 it lightly tidies the note without the flow loss of a chambered muffler. With the cat removed, the system is still very open; the hotdog just trims the rawest resonance off an otherwise loud, free-breathing 3in run from the turbo back.
No. It deletes the catalytic converter on a turbo-back system, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. The cat is the emissions hardware the Cannon left the factory with; removing it means the ute can't be run registered on public roads. We fit this for off-road vehicles only.
Turbo-back means the run from the turbo outlet rearward is replaced in 3in pipe, so the larger bore begins where a small 2.0L diesel is most restricted. Deleting the cat opens that path further; the hotdog is the only damping device in the line on this configuration.
Oak Flats Muffler Men supplies and fits these systems in-house across the Illawarra for off-road use. We confirm the Cannon's 2020–2025 build, check hanger and hotdog clearance, and advise on whether a cat-delete suits how you use the ute before booking the bay.
