Nissan Patrol Warrior Y62 V8 5.6L Wagon 3in Full Exhaust System, Muffler Centre & Bi-Modal.
Category: Mufflers and resonators


The most subdued of the valved full systems, the MPI Automotive SSMKNI0128 runs a chambered centre muffler in its full 3in cat-back for the Nissan Patrol Warrior Y62 V8 5.6L wagon, with a bi-modal valve at the rear for switchable volume.
A chambered muffler quietens by reflecting and absorbing exhaust pulses inside a baffled box, so it broadly lowers volume rather than targeting a single frequency the way a resonator does. On the SSMKNI0128 that mid-system muffler makes this the calmest of the full Y62 builds when the valve is closed — the 5.6L V8 stays well-mannered, then the bi-modal valve lets it open up on demand.
The bi-modal valve at the rear switches the exhaust between a quieter path and a more open one. Paired with a chambered centre muffler, the SSMKNI0128 gives the widest swing in this family: genuinely quiet in closed mode, with the valve unlocking a louder note. It's a complete 3in cat-back, replacing the system rearward of the cats.
It's listed to fit the Nissan Patrol Warrior Y62 V8 5.6L wagon. Confirm your exact Warrior build and any accessory clearance with the workshop before ordering — listed fitment is a starting point, not assured across every variant.
Oak Flats Muffler Men supplies and fits these valved Y62 cat-backs in-house across the Illawarra. We check the muffler and valve positions, hanger alignment and tailpipe clearance on the wagon body, then book the bay once fitment is confirmed.
