Two silencers, one tuned each way: the MPI Automotive MKNI0106 is a full system for the Nissan Patrol GU 4.5L that runs no cat but pairs a centre muffler with a rear hotdog. The muffler-plus-hotdog combination is the defining feature — the muffler softens, the hotdog keeps flow up, landing a balanced note.

Why pair a centre muffler with a rear hotdog?

The two silencers do different jobs. The centre muffler quietens by absorption, taking the harshest volume out of the GU's note, while the rear hotdog — a compact straight-through resonator — trims drone at the tailpipe without packing the flow back down. Run together on this full system they balance each other: more open and characterful than a twin-muffler setup, but more civilised than a hotdog-only build. It suits a GU 4.5L owner who wants flow and voice without the cabin booming.

Is the MKNI0106 road legal in NSW?

No. This full system runs without the catalytic converter on a road-relevant exhaust path, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road or competition use only. The two silencers manage sound, not emissions — deleting the cat removes the hardware the Patrol left the factory with, and that can't be softened for registration. Ask the workshop about a with-cat build if you need to stay road-legal.

Will it fit my GU 4.5L Patrol?

It's listed to fit the Nissan Patrol GU 4.5L as a full system with a centre muffler and rear hotdog. The supplier doesn't publish the bore or year range on this listing, so we won't quote a diameter — confirm your exact GU build with the workshop before we order, since feed data can be imperfect and we'd rather verify the actual vehicle.

What's involved in fitting it in the Illawarra?

Oak Flats Muffler Men supplies and fits this MPI Automotive full system at our Oak Flats workshop. We'll check the routing, the centre-muffler and rear-hotdog clearances under your GU Patrol, confirm the fitment against your vehicle, and talk through the off-road-only use before booking the bay.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.

Common questions

Why does the MKNI0106 have two silencers?
The centre muffler softens volume by absorption and the rear hotdog trims drone without choking flow. Together they balance a fuller note against cabin comfort.
Can I register a GU with this fitted?
No. It runs without the catalytic converter, so it isn't ADR 79/04 compliant for road registration in NSW and is for off-road use only.
What bore is it?
The supplier doesn't publish the diameter on this listing. Confirm the spec and fitment for your GU 4.5L with the workshop before ordering.
