Built at 2.5in for the petrol Nissan Patrol GU 4.8L, the MPI Automotive SSMKNI0101 is a full system with a centre muffler, a rear hotdog and provision for four O2 sensors. The 2.5in bore suits the inline-six 4.8L without over-sizing the run.

Why 2.5in on the 4.8L petrol six?

At 2.5in this full system is sized to the 4.8L petrol straight-six in the GU — a bore that keeps gas speed up across the rev range rather than chasing a bigger pipe the engine doesn't need. It is the only diameter we state, because it is the only one in the record. The run pairs a chambered centre muffler with a rear hotdog, so the middle stays subdued while the rear resonator keeps the tailpipe tidy.

What do the four O2 sensor bungs mean?

The SSMKNI0101 is set up for four O2 sensors, matching the 4.8L's sensor layout so the factory fuelling and diagnostics carry over cleanly without throwing fault codes. A centre muffler quietens the middle of the run by absorption and reflection, while the rear hotdog — a compact straight-through resonator — tidies the tail without choking flow.

Will it suit my Patrol GU 4.8L?

It is listed to fit the Nissan Patrol GU 4.8L. Series and years aren't published by the supplier, so this is a listed-to-fit guide rather than a guarantee — confirm your exact build and sensor arrangement with the workshop before ordering.
