Does the MKNI0040 keep the catalytic converter?

Yes. This is a with-cat, with-muffler section, so the GU Patrol's factory catalytic converter stays in place and the emissions hardware is retained.

Will it fit a GU Patrol ute?

It's listed for the GU ZD30 in wagon body. Ute floors and routing differ, so confirm your exact body and build with the workshop before ordering.

Is this a loud system?

No. It runs a rear muffler and keeps the cat, so it's the quieter, more liveable build rather than a stripped-out, louder setup.

The MPI Automotive MKNI0040 is a cat-and-muffler exhaust section listed to fit the GU Patrol ZD30 in wagon body. It keeps the catalytic converter and runs a rear muffler, so it's the civil, emissions-retaining build rather than a loud, stripped-out one.

What makes this the with-cat, muffler build?

Where a Patrol owner can chase a hard, raucous note by deleting hardware, the MKNI0040 deliberately goes the other way. It retains the catalytic converter the GU wagon left the factory with and finishes through a muffler, so the absorptive/chambered body soaks up the harsher edges of the ZD30's diesel note. The result is a tidier, more liveable tone for a wagon that's likely doing touring and family duty rather than weekend track work.

What does the muffler actually change on a ZD30?

A muffler quietens by reflection and absorption — it's the part of the system that tames drone and rasp without choking flow the way a tired factory box can. On the GU ZD30 wagon this matters on long highway hauls, where an unmuffled diesel can boom inside the cabin. Keeping the cat in place means the emissions side stays as Nissan intended, so this is the build for owners who want freshened pipework without the off-road-only compromises.

Will it suit my GU Patrol wagon?

It's listed to fit the Nissan Patrol GU ZD30 in wagon configuration. Body shape matters on a Patrol because the wagon's rear floor and tow-bar routing differ from a ute, so send your exact build, year and any existing modifications and we'll confirm the run before ordering. Fitment data is a guide, not a guarantee.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the MKNI0040 in-house across the Illawarra. We check hanger positions, clearances over the rear axle and crossmember, and confirm the cat and muffler sit correctly before signing off. The RRP is AUD 1761.14; tell us your GU wagon's spec and we'll book the bay.
