Does the MKNI0115 keep the cat and a resonator?

Yes — it retains the factory catalytic converter and uses a hotdog resonator instead of a full muffler.

How quiet is the hotdog?

It softens the note while staying free-flowing — more subdued than a no-muffler build. We can't put a number on it; hear a comparable fit at the workshop.

The MPI Automotive MKNI0115 is the most road-friendly layout in the Navara D22 2.5L set — it keeps the catalytic converter and runs a hotdog resonator, aiming for a tidied note rather than a stripped-out one.

Why pair the cat with a hotdog?

Of the 2.5L variants, this is the one that keeps the most factory hardware: the catalytic converter stays, and a hotdog resonator handles the silencing instead of a full chambered muffler. The hotdog is a compact straight-through unit — a perforated core in absorptive packing — that knocks the hard edge off the diesel note while staying free-flowing. Retaining the cat keeps the emissions equipment the ute was registered with in place, which is what marks the MKNI0115 out from the cat-delete builds in the family.

Will it suit my Navara D22 2.5L?

It's listed to fit the Nissan Navara D22 with the 2.5L engine. Years aren't published by the supplier for this listing, so confirm your exact build and year with the workshop before ordering — we'd sooner check than have you rely on a span the record doesn't carry.

Is it road legal?

The MKNI0115 keeps the catalytic converter, the emissions component most relevant to keeping a diesel ute registered, so that hardware stays as delivered. Final compliance is judged on the whole vehicle and current NSW rules, so confirm your intended use with the workshop before fitting.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits the MKNI0115 in-house across the Illawarra. We seal the cat flange, position the hotdog clear of the chassis and set the hangers so the resonator sits without loading the body. Send your build details and we'll confirm the fitment and book the work.
