Nissan NP300 Navara 3in Turbo Back Exhaust System With Cat, WOM.
Category: Complete exhaust systems


The MPI Automotive MKNI0091 is a 3in turbo-back system listed to fit the Nissan Navara NP300. It retains the catalytic converter and runs without a centre muffler, so confirm the build that suits how the vehicle is used.
A turbo-back run replaces the exhaust from the turbo outlet rearward, which is a longer span than a cat-back and the point where a turbocharged engine tends to breathe more freely. The MKNI0091 is sized at 3in for the Nissan Navara's engine, keeps the factory catalytic converter in the system. It is set up without a centre muffler, so expect a fuller note than the standard system.
A turbo-back exhaust covers everything from the turbocharger outlet to the tip, which is the most complete path a bolt-on system can take on a turbo-diesel. Going to a larger 3in bore reduces restriction across that full length, and removing or relocating a muffler changes the character of the note rather than just the volume. The trade-off is that a longer, less restrictive system can sound busier in the cabin and, where it deletes emissions hardware, moves the vehicle out of the road-registrable category. Which way you go depends on whether the Nissan Navara is a daily registered vehicle or a dedicated off-road build.
This build retains the catalytic converter, which keeps the main emissions component the Nissan Navara left the factory with in place — the usual sticking point for compliance. That is not a guarantee of registration in itself, so confirm the exact build and any state requirements with the workshop before fitting.
