How does this differ from a twin-hotdog Patrol system?

The SSMKNI0105 uses a chambered centre muffler rather than a centre hotdog, so it leans quieter and more subdued through the middle of the system.

Is the catalytic converter affected?

The supplier doesn't publish cat detail for this listing, so confirm the cat arrangement and road-use intent with the workshop before ordering.

Pairing a chambered centre muffler with a rear hotdog, the MPI Automotive SSMKNI0105 is a full exhaust system for the Nissan Patrol GU 4.5L. The muffler-then-hotdog layout keeps the note more subdued up front while the rear resonator handles the tail.

Why a centre muffler with a rear hotdog?

The SSMKNI0105 places a chambered muffler in the centre — which quietens by reflection and absorption — and finishes with a rear hotdog, a compact straight-through resonator that cleans up harshness near the tailpipe. The result is a more restrained character than a twin-hotdog system, with the muffler doing the heavier lifting on volume while the rear unit keeps the tail tidy. No decibel figures are published, so we describe it by the layout rather than a number.

What does a full system replace?

This is a full exhaust system for the GU 4.5L, so it covers the run rather than a single section — a sensible swap when the original has rusted through in more than one place. Bore and material are not published by the supplier; we describe only what the record gives — a centre muffler, a rear hotdog and a full-length fit on the 4.5L.

Will it suit my Patrol GU 4.5L?

It is listed to fit the Nissan Patrol GU 4.5L. With series and years not published, this is a listed-to-fit guide rather than a guarantee — confirm your exact variant with the workshop so we can match the system to your build before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits full Patrol systems in-house across the Illawarra. We mock up the centre muffler and rear hotdog positions under the GU, check clearances and hangers, and verify the listing against your vehicle before the bay is booked. As a made-to-order full system it is ordered in against your build.
