Nissan Pathfinder R51 2.5L THAI With Cat (SKU: MKNI0058) Engineered. Quality guaranteed.
Category: Complete exhaust systems


Listed at $2225.65, the MPI Automotive MKNI0058 is a with-cat exhaust for the Thai-built Nissan Pathfinder R51 2.5L. It retains the catalytic converter.
This is the with-cat exhaust for the R51 Pathfinder with the 2.5L engine, the Thai-built version. It keeps the catalytic converter in the run, so it holds the factory emissions hardware in place rather than removing it. MPI Automotive doesn't publish the bore, material or full component list for this listing, so the workshop confirms what's supplied against the R51 before ordering rather than quoting figures that aren't given.
The R51 Pathfinder shares a platform generation with the D40 Navara and was built across more than one plant, so build origin decides which system lines up. This part is matched to the Thai build, which keeps the connections and hangers where the factory put them — get the origin wrong and the routing can fight the mounts.
It retains the catalytic converter, which is usually the deciding factor for compliance because the cat is what road registration in NSW depends on. That isn't a guarantee of registration on its own, so confirm the exact build and any state requirements with the workshop before fitting.
