Is the centre muffler quieter than the hotdog option?

Yes — a chambered muffler quietens by absorption and reflection, so it's more subdued than a straight-through hotdog centre section. We can walk you through which suits the note you're after on your Patrol.

Does it work with the Warrior's bi-modal valve?

It's built for bi-modal integration on the Y62 Warrior, so it's designed to sit alongside that valved setup. Confirm exactly what your build needs with the workshop.

The MPI Automotive MBM629MF is a 3in centre muffler with bi-modal integration, listed to fit the Nissan Patrol Warrior Y62 5.6L V8. Where a hotdog flows straight through, this is the chambered centre muffler — the choice for a more subdued centre section that still answers the Warrior's bi-modal valve.

What does a centre muffler do here?

A muffler quietens by absorption and reflection — gas is routed through chambers and packing that cancel and soak up sound rather than passing straight through. As a centre section on the Y62's 5.6L V8, the MBM629MF is the more restrained option: it pulls the note back compared with a straight-through resonator while still feeding the rest of the system. It's the part to pick when you want the middle of the exhaust working to calm the note.

How does it work with the bi-modal valve?

This centre muffler is built for bi-modal integration on the Warrior, so it sits alongside the valve that switches the system between a quieter and a louder path. Pairing the chambered muffler with that switching gives a centre that leans subdued by default and still opens up when the valve does — a different balance from the straight-through hotdog version, which starts more open. The valve does the loud-or-quiet switching; the muffler sets how restrained the baseline is.
