What size is the MKNI0003?

It's built around a 3in bore — the larger-bore step that suits a diesel ute wanting freer flow than the stock-size pipe.

Does it keep the catalytic converter?

Yes. This is a with-cat, with-muffler system, so the D22's factory catalytic converter stays in place.

Will the muffler keep it quiet?

The muffler tames the 3in pipe by absorption and reflection, so it stays more liveable than an unmuffled big-bore build. We can't quote a decibel figure.

Built around a 3in bore, the MPI Automotive MKNI0003 is a with-cat, with-muffler exhaust listed to fit the Nissan Navara D22 2.5L. The 3in sizing is the headline here: it's the larger-bore step that suits a diesel ute chasing freer flow over a stock-size pipe.

What does the 3in bore suit?

Bore is the defining attribute of this section. At 3in it's sized for a diesel like the D22 2.5L that benefits from a bigger path than the factory pipe, giving the turbo a less restrictive route out. Larger bore tends to favour mid-range and top-end breathing on a modified or hard-worked engine. It's paired with a muffler, so the bigger pipe doesn't come at the cost of cabin manners — the muffler keeps the note in check.

Why with-cat and with-muffler?

This build keeps the catalytic converter, so the emissions hardware the D22 left the factory with stays in place — the road-relevant side of the equation. The muffler then quietens the 3in pipe by absorption and reflection, taming the rasp a big-bore diesel can otherwise produce. Together that makes the MKNI0003 the breathe-freer-but-stay-civil option rather than a stripped, loud one.

Will it suit my Navara D22?

It's listed to fit the Nissan Navara D22 with the 2.5L engine. D22s span a long production run with detail differences, so send your exact build and year and we'll confirm the 3in run, hanger points and cat position before ordering. Listed fitment is a guide, not a guarantee.

What does fitting involve in the Illawarra?

Oak Flats Muffler Men supplies and fits the MKNI0003 in-house. We confirm the 3in pipework clears the chassis and crossmember, check the muffler and cat sit correctly, and set the hangers before sign-off. RRP is AUD 1885.20; tell us your D22 2.5L's spec and we'll book it in.
