Does the SSMKNI0095 keep the catalytic converter?

Yes — it's the with-cat turbo-back, so the factory catalytic converter stays in place. Confirm any state requirements with the workshop.

How does it differ from the without-cat version?

This SSMKNI0095 retains the cat; the cat-delete version omits it and is off-road only. The with-cat option keeps the emissions hardware for road use.

What's the pipe size?

It's a 3in turbo-back with a rear muffler, listed for the Nissan NP300 Navara.

The MPI Automotive SSMKNI0095 is a 3in turbo-back system for the Nissan NP300 Navara that keeps the catalytic converter and runs a rear muffler. Retaining the cat is the headline here: it leaves the Navara's emissions hardware in place, which is the path most owners want for a vehicle that stays registered and on the road.

What does a with-cat turbo-back cover?

A turbo-back replaces the exhaust from the turbo outlet rearward — the full span where a 3in bore frees up flow on the NP300's diesel. This version retains the catalytic converter and finishes through a rear muffler, so it's the engine-back upgrade that keeps the factory emissions equipment where Nissan fitted it. Confirm exact state requirements with the workshop, but keeping the cat is the key compliance-friendly choice on a diesel ute.

Why the 3in bore and a rear muffler?

The 3in diameter is sized for the Navara's diesel output, giving a freer-flowing run than a tired factory system. The rear muffler keeps the note measured rather than open, so the result is a cleaner exhaust without going raucous. Because the cat stays, this is the version to look at when the ute is driven on the road rather than off it. Sound comes from the layout — we publish no decibel figure.

Will it suit my NP300 Navara?

The SSMKNI0095 is listed to fit the Nissan NP300 Navara. As with any turbo-back, the join at the turbo outlet and the rearward routing need to match your exact build, so send your details through and we'll confirm clearances before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits turbo-back systems in-house across the Illawarra. We mate the 3in run to your turbo outlet, retain and reconnect the catalytic converter, and set the rear muffler and hanger clearances on the NP300. Book the bay and we'll have it fitted in one visit.
