NISSAN PATROL GU 4.8L TB48 PETROL WAGON

As many 4.8L petrol GU Patrol owners have found, the best way to improve their car overall, is by fitting the full Manta exhaust kit to their vehicle.
\n
\nAlthough the 4.8L is very reliable, power and torque left a little to be desired, and it had rather heavy fuel consumption. Therefore many owners look for ways to improve the power and economy of their vehicle. An easy way to do this, is to fit the Manta 2.5″ exhaust. This mandrel bent, high flow system replaces the entire standard exhaust system (a high flow extractor replaces the standard cast manifold) to give you better sound, and much more flow.
\n
\nThis leads to increased performance, as the engine is able to operate much more efficiently. The twin muffler setup used ensures that there is no drone inside the cabin, although the system does give the car a lovely deep sounding exhaust tone when heard from outside. The exhaust is also available as a “cat back” system, replacing the last two parts of the factory exhaust for those just chasing an improved engine sound.
