Category: Mufflers and resonators


The MPI Automotive MKNI0128 is the quiet-biased full system for the Nissan Patrol Warrior Y62 V8 5.6L wagon: a 3in cat-back with a chambered centre muffler and a bi-modal valve that unlocks the louder side when you want it.
A chambered muffler quietens broadly by reflecting and absorbing exhaust pulses inside a baffled box, rather than targeting one frequency. On the MKNI0128's full 3in cat-back, that makes it the most subdued of the full Y62 builds in closed mode — the 5.6L V8 stays well-mannered for daily and towing duty. It's the choice when a quiet baseline matters.
The bi-modal valve switches the exhaust between a quieter and a more open path. Combined with a chambered centre muffler, the MKNI0128 gives the widest swing of the range: genuinely quiet when closed, with the valve releasing a louder note on demand. It's a complete cat-back, 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, hangers and tailpipe clearance on the wagon, then book the bay once fitment is confirmed.
