Nissan Patrol Warrior Y62 V8 5.6L Wagon 3in Catback With Muffler & Bi-Modal Integration.
Category: Mufflers and resonators


The MPI Automotive SSMKNI0122 is a complete 3in cat-back for the Nissan Patrol Warrior Y62 V8 5.6L wagon built around a chambered centre muffler — the most restrained of the cat-backs — with bi-modal valve integration for switchable volume.
A chambered muffler quietens broadly by reflecting and absorbing pulses in a baffled box, rather than targeting one frequency like a resonator. In the SSMKNI0122's full 3in cat-back, that makes it the calmest of the Y62 cat-backs in closed mode — the 5.6L V8 stays well-mannered for daily and towing duty, then the bi-modal valve lets it open up.
The bi-modal valve switches the exhaust between a quieter path and a more open one. Paired with a chambered centre muffler, the SSMKNI0122 offers a wide swing: genuinely subdued when closed, louder when the valve opens — a complete system rearward of the cats, not a centre section.
It's listed to fit the Nissan Patrol Warrior Y62 V8 5.6L wagon, replacing the system rearward of the cats. Confirm your exact Warrior build, towing setup and valve wiring with the workshop before ordering, as fitment data can be imperfect.
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, then book the bay once your Patrol's build is confirmed.
