The latest Y62 Nissan Patrol, is available with a 5.6L V8 petrol motor only, and has developed a reputation for being a gas-guzzler. A prime reason for this is the overly-restrictive factory exhaust system, which uses no fibreglass packing, but rather a complex system of chambers, baffles and valves to control the exhaust noise.
As a result, the fuel economy suffers as the engine is unable to breathe properly, and the exhaust note is wheezy, and hardly befitting of a V8.
The newly developed Manta exhaust system runs from the cats back, in dual 2.5″ mandrel bent pipe-work, and then into single 3″ pipe-work, with two straight-through glass packed mufflers to keep the noise down.
The result is a fantastic sounding exhaust note, that is not loud at all and far from instrusive inside the cabin. Best of all, the free-flowing design gives a dynoed increase of up to 22hp, while simultaneously reducing fuel consumption by up to 4L/100km.
The system has been specially developed with a 2 piece rear section design to allow fitment to vehicles with a long range tank. While the cat back delivers the best sound, the centre muffler delete is an alternative option which retains the rear section of the factory exhaust, but still gives the benefit of bigger pipe work off the cats, and a straight through centre muffler.
The Y62 Patrol has 4 catalytic converters in total. The resonated cat delete pipes are intended for off road or race use, giving you the option to remove the second set of cats for a louder, throatier sound, better flow, and improved fuel consumption.
