Is the MKNI0105 a full system or a cat-back?

It's a full system — it replaces the exhaust as a complete run rather than only the section behind the cat.

What's the muffler layout?

A chambered centre muffler does the main silencing and a free-flowing rear hotdog finishes the system.

The supplier doesn't publish a diameter for this listing; we confirm pipe size at fitting.

The MPI Automotive MKNI0105 is a full exhaust system for the Nissan Patrol GU 4.5L, with a centre muffler and a rear hotdog. As a full system it renews the run end to end rather than just the section behind the cat.

What does a full system change over a cat-back?

Where a cat-back only replaces from the catalytic converter rearward, a full system replaces the exhaust as a complete length. That means every section, joint and hanger is new, so there's no mating fresh pipe to tired factory sections. On the 4.5L GU Patrol it's the thorough option for a vehicle whose original exhaust may be well-worn after a long working life.

How are the muffler and hotdog arranged?

The centre muffler is a chambered, absorptive silencer that handles the main quietening through the middle of the car. The rear hotdog is a short straight-through resonator that flows freely and lets the note exit cleanly at the back. Together they give a controlled tone with a freer rear exit than a two-muffler layout.

Will it suit my Nissan Patrol GU?

It's listed to fit the Nissan Patrol GU with the 4.5L engine. The supplier doesn't publish a diameter for this listing, so pipe size is confirmed at fitting rather than guessed here; the GU also had a long, updated production run, so confirm your exact build with the workshop first.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this full system in-house across the Illawarra. As a full-length fit it's more involved than a cat-back; we check every hanger and clearance point on the GU body and confirm the build before booking the bay.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
