Does the SSMKNI0115 keep the cat and add a resonator?

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

How quiet is the hotdog?

A hotdog softens the note while staying free-flowing — more subdued than a no-muffler build, but we can't put a number on it. Hear a comparable fit at the workshop.

The MPI Automotive SSMKNI0115 pairs a retained catalytic converter with a hotdog resonator for the Nissan Navara D22 2.5L — the cat-in, hotdog-silenced build that aims for a tidied note rather than a stripped-out one.

What's the cat-plus-hotdog combination for?

This is the most road-friendly layout in the 2.5L set: 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 — so it knocks the hard edge off the diesel note while staying free-flowing. Keeping the cat means the emissions hardware the ute was registered with remains in place, which sets the SSMKNI0115 apart from the cat-delete versions of the same part.

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 rather check than have you assume a range the record doesn't carry.

Is it road legal?

The SSMKNI0115 keeps the catalytic converter, the emissions component most relevant to keeping a diesel ute registered. Retaining the cat leaves that hardware 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 SSMKNI0115 in-house across the Illawarra. We seal the cat flange, set the hotdog clear of the chassis and check the hangers so the resonator sits without loading the body. Send your build details and we'll confirm the fitment and book the work.
