Does the SSMBM630PHD keep the catalytic converters?

No — it is a cat-replacement pipe set, so it takes the place of the factory converters. That makes it off-road use only and not ADR 79/04 compliant for road registration in NSW.

Is this a muffler or a resonator?

Each pipe carries a resonator, which is a frequency-tuning device rather than a full chambered muffler. It reduces drone without quietening the V8 the way a muffler would.

Will it fit my Nissan Patrol Y62?

It's listed to fit the Y62 5.6L V8. Confirm your exact variant with Oak Flats Muffler Men before ordering.

These are cat-replacement pipes with a resonator, the MPI Automotive SSMBM630PHD, listed to fit the Nissan Patrol Y62 5.6L V8. They take the place of the factory catalytic-converter section and run a resonator in each pipe rather than a full muffler.

What does replacing the cat section change?

The SSMBM630PHD swaps out the converter pipes the petrol Y62 V8 left the factory with, so it changes the emissions hardware on the car rather than just the silencing. The dual layout keeps the V8's left and right banks separate back through the resonator stage, and the resonator is there to settle the tone rather than to silence it the way a chambered muffler would. It's a section that buyers fit when they're building a freer-flowing Y62 system and want the converters out of the path.

Is this road legal in NSW?

Removing the factory catalytic converters affects emissions compliance — a vehicle running cat-replacement pipes in place of its converters is not ADR 79/04 compliant for road registration in NSW, and is intended for off-road or competition use. We won't soften that. If your Patrol is registered and driven on the road, the converters need to stay, so talk to us about your intended use before ordering this part.

What does a resonator do here?

A resonator is a tuning device, not a silencer — it targets specific frequencies to take the edge off a drone or harshness while leaving the V8's character largely intact. On the big 5.6L it sits inline in each pipe to keep the note civil without the bulk or volume drop of a full muffler, which is why it pairs with cat-replacement pipes aimed at flow.

Will it suit my Patrol Y62?

It's listed to fit the Nissan Patrol Y62 with the 5.6L V8; confirm the exact build with the workshop before you commit. Oak Flats Muffler Men supplies and fits these in-house across the Illawarra, and we'll check the existing exhaust path, flange faces and hanger points on the hoist first. The RRP is listed, and because it's an off-road section we'll talk through the compliance side at the same time.
