Is the SSMKNI0068 road legal?

No. It deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only.

How loud is it compared with a hotdog system?

It runs twin chambered mufflers, so it leans quieter and more subdued than a hotdog-based Patrol system.

Does it fit my GU 4.5L?

It is listed to fit the Patrol GU 4.5L. Confirm your exact build with Oak Flats Muffler Men before ordering.

The MPI Automotive SSMKNI0068 is a no-cat full system for the Nissan Patrol GU 4.5L running twin chambered mufflers — centre and rear. The dual mufflers make it the most subdued of the GU 4.5L full-system options, while the cat delete sets its road status.

Why two mufflers on a full system?

The SSMKNI0068 places a chambered muffler at the centre and another at the rear, each quietening by absorption and reflection. Two of them along a full-length system give the quietest-leaning character among the GU 4.5L options — a contrast to a hotdog-based system, which flows freer and runs harder. No decibel figures are published, so we describe it by the layout rather than a number.

Is it road legal in NSW?

No. This is the no-cat full system, so it deletes the catalytic converter. That makes it not ADR 79/04 compliant for road registration in NSW and it is for off-road use only. A road-registered Patrol must keep its emissions hardware in place — there is no softening of that, so this system suits off-road, competition or private-property use rather than a registered vehicle.

Will it suit my Patrol GU 4.5L?

It is listed to fit the Nissan Patrol GU 4.5L. Bore, series and years aren't published by the supplier, so this is a listed-to-fit guide rather than a guarantee — confirm your exact build with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits full Patrol systems in-house across the Illawarra. Because this one deletes the cat, we'll confirm your intended use, mock up the centre and rear muffler positions, and verify the listing against your GU before booking. As a made-to-order full system it is ordered in against your build.
