Can I register a Navara with the SSMKNI0118 fitted?

No. It deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only.

Why is there no muffler?

This version is built without a rear muffler, giving the most open path in the family. That suits an off-road ute, not a quiet daily.

Which engine does it fit?

It's listed to fit the Nissan Navara D22 2.5L. Years aren't published — confirm your exact build with us first.

The MPI Automotive SSMKNI0118 is the stripped-out, free-flow version for the Nissan Navara D22 2.5L — no catalytic converter and no muffler, so it's the most open exhaust path in this family. Because it deletes the cat, it is an off-road-only build.

Is it road legal?

No. The SSMKNI0118 deletes the catalytic converter on a road-relevant exhaust, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road use only. There is no softening of this — removing the cat removes emissions hardware the ute was registered with. We'll talk you through where a build like this can and can't be used before you commit.

What does deleting the cat and muffler change?

With both the catalytic converter and the rear muffler gone, this is the least restrictive layout in the D22 2.5L family — a clean, open pipe from front to tail. That means the most natural diesel note and nothing absorbing or reflecting sound at the rear. It's the choice for an off-road or competition ute where the cat and silencing aren't required, not for a daily-driven, registered vehicle.

Will it suit my Navara D22 2.5L?

It's listed to fit the Nissan Navara D22 with the 2.5L engine. The supplier doesn't publish years for this listing, so confirm your exact build and year with the workshop before ordering — don't assume a span the record doesn't state.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the SSMKNI0118 in-house across the Illawarra, for off-road use. We confirm the application, set the hangers for a muffler-delete tail and check clearance along the chassis. Tell us how the ute is used and we'll confirm the fitment is appropriate before booking.
