What's the note like on the MKNI0067?

The centre muffler softens the volume and the rear hotdog keeps flow up while trimming drone. It lands a balanced note — fuller than a twin-muffler system, more civilised than an open one.

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.

Will it fit my Patrol?

It's listed to fit the GU 4.5L as a full system. Confirm your exact build with the workshop before ordering.

The MPI Automotive MKNI0067 splits its silencing duties: a centre muffler to soften the note and a rear hotdog to keep flow up, across a full system for the Nissan Patrol GU 4.5L. That muffler-front, hotdog-rear pairing is the defining feature — a balanced middle between a quiet twin-muffler build and an open hotdog one.

How do the centre muffler and rear hotdog work together?

The centre muffler quietens by absorption, taking the harshest volume out of the GU's 4.5L note, while the rear hotdog — a compact straight-through resonator — passes gas through a perforated core to trim drone at the tailpipe without choking flow. Run together on this full system they balance each other: more open and characterful than a system with two mufflers, but more civilised than one running hotdogs throughout. It suits a GU owner chasing a bit of voice and flow without constant cabin boom.

What does the full system cover?

As a full system the MKNI0067 replaces the run end to end on the GU 4.5L, with the centre muffler and rear hotdog in place. The supplier doesn't publish the bore here, so we won't quote a diameter — the silencer layout is the defining detail, not the pipe size.

Will it suit 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 a year range, so confirm your exact GU build with the workshop before we order — listed-to-fit covers the engine and model, but we verify the actual vehicle rather than trust feed data.

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 confirm the routing and the centre-muffler and rear-hotdog clearances under your GU Patrol, check the fitment against your vehicle, and book the bay once it's confirmed.
