Nissan Pathfinder R51 2.5L SPANISH Without Cat.
Category: Complete exhaust systems


MKNI0061 is an MPI Automotive exhaust listed to fit the Spanish-built Nissan Pathfinder R51 2.5L, and it is the cat-delete configuration of the R51 listing rather than the converter-retained one.
The MKNI0061 is listed against the Nissan Pathfinder R51 2.5L in the Spanish-built form — worth flagging, because the R51 was assembled in more than one plant and the pipework can differ between builds. The supplier does not publish the pipe material or the full component breakdown for this listing, so we read those off the vehicle rather than guess them from the title. Send us the chassis details and we confirm the listed fit lines up with your actual Pathfinder before anything is ordered.
This particular R51 listing is built without the catalytic converter. On a road-driven car that converter is the emissions component the Pathfinder left the factory with, and removing it pushes the vehicle out of the road-registrable category. We treat the MKNI0061 as an off-road or competition fitment, not a swap for a daily-driven, registered R51 — and if your Pathfinder has to stay on the road, we will point you at a converter-retained alternative instead of softening that.
Stripping the converter out of the run is the most open way this part can be specified: less restriction through the section the cat used to occupy, and a louder note relative to the standard R51 system. It is a change to flow and tone on a 2.5L Pathfinder, not a tune or a mechanical fix, so think of it as suiting a vehicle that already lives off the blacktop.
Oak Flats Muffler Men, here in the Illawarra, brings this MPI Automotive part in to order and fits it in our own bays. We check the listed R51 fitment against your Spanish-built Pathfinder, confirm the cat-delete configuration is genuinely what the vehicle is being used for, and confirm current pricing and lead time with you before committing the order.
