Manta Exhausts for the Nissan Patrol GU
Manta lists separate systems for each GU Patrol engine, because the engine changed during the GU's run. The 4.5L TB45 petrol (1998 to 2001) and the later 4.8L TB48 petrol use a 2.5 inch mandrel-bent system with a high-flow extractor in place of the cast manifold and a twin-muffler layout to limit cabin drone. Both are offered as a cat-back or a full system. Diesel GUs include a 2.8L turbo diesel with a 3 inch turbo-back and a 4.2L naturally aspirated option. Confirm your engine code before ordering.
Manta Exhausts for Navara D40 and D23 NP300
The D40 YD25 2.5L turbo diesel can take a full 3 inch system from the turbo face through to the tail, including the dump pipe, with the turbo-back kit including recalibrated DPF sensors and intended for off-road use. The D23 NP300 2.3L is offered as a pipe-only DPF-back for maximum sound or as a turbo-back with quiet, medium and loud variants. Our Navara exhaust guide compares every generation.
Choosing the Right Nissan System
Cat-back and DPF-back systems suit owners who want to keep their factory components, while turbo-back and full systems replace more of the exhaust for greater flow. Compliance depends on the vehicle, its installation and your state or territory rules, so check before choosing a system that removes emissions equipment. Read our exhaust types guide, browse 4x4 exhaust systems, and add exhaust gaskets and exhaust rubbers to finish the job. Book fitting through our exhaust fitting page.
Sound Levels, Materials and Warranty
Petrol Patrol systems use a twin-muffler layout for a deep note outside the car with limited drone inside, while D23 turbo-back systems offer quiet, medium and loud options using a high-flow muffler, a hotdog muffler or pipe only. Systems come in aluminised or stainless steel depending on the listing, and warranty terms vary by material and part number.
