What sets the MPI Automotive MKNI0101 apart is its provision for 4x O2 sensors — it's a 2.5in full system for the Nissan Patrol GU 4.8L that caters to the four-oxygen-sensor setup, with a centre muffler and a rear hotdog.

Why does the 4x O2 sensor provision matter?

Some GU Patrol 4.8L builds run four oxygen sensors, and a replacement system has to provide the right bungs in the right places so each sensor reads correctly. The MKNI0101 is listed for that four-sensor arrangement, which is the detail that separates it from a system built for fewer sensors. Matching sensor provision is what keeps the engine management reading exhaust gas the way the factory intended.

What does a 2.5in full system cover?

As a full system it replaces the exhaust as a complete length — every section, joint and hanger renewed rather than mating new pipe to old. At 2.5in it's sized for the 4.8L petrol six, a sensible bore for a heavy 4x4 that works loaded and towing rather than chasing maximum flow.

How are the muffler and hotdog arranged?

The centre muffler is a chambered absorptive silencer that does the main quietening in the middle of the car, and the rear hotdog is a free-flowing straight-through resonator that lets the note exit cleanly at the back — a controlled tone with a freer rear exit than a twin-muffler layout.

Will it suit my GU, and who fits it?

It's listed to fit the Nissan Patrol GU 4.8L with the four-O2-sensor setup; confirm your sensor arrangement and exact build with the workshop first, as the GU varied across its long run. Oak Flats Muffler Men supplies and fits this full system in-house across the Illawarra.
