Nissan Navara D40 2.5L MAN 05 - 07 Without Cat R Tail (SKU: SSMKNI0007) Engineered. Quality guaranteed.
Category: Complete exhaust systems


Carrying an indicative RRP of 2640.55 AUD, the MPI Automotive SSMKNI0007 is a without-cat exhaust listed to fit the Nissan Navara D40 2.5L manual built in the 05–07 window, finishing in a rear tailpipe. The cat-delete configuration is the line that sets it apart from the with-cat early-D40 listings.
The 05–07 range pins this to the first phase of the D40 Navara, paired here with the manual gearbox — both details that the listing is built around. The early manual cars routed their own way, which is why MPI Automotive carries a distinct part number for them. Engine is given as 2.5L; diameter and material are not published, so we don't quote figures the supplier hasn't stated.
This SSMKNI0007 leaves the catalytic converter out and ends in a rear tailpipe rather than a rear muffler box. Without the cat, the emissions hardware the D40 wore from new is no longer in the system, so this is the off-road-oriented build in the early-manual range. The rear-tailpipe ending is a layout choice, not a tone we can measure — no sound data is published, so we won't characterise the note.
It's listed to fit the Nissan Navara D40 2.5L manual from 05–07; send us your exact year, gearbox and build and we'll match it before anything is ordered, since feed data can be imperfect. If you'd rather keep the cat, there are with-cat tailpipe and muffler versions in the same early-D40 family.
Oak Flats Muffler Men special-orders the SSMKNI0007 through MPI Automotive and fits it in-house across the Illawarra. We confirm the early-manual fitment and current pricing before placing the order, and fit cat-delete systems on the understanding they're for off-road use.
