NISSAN PATROL GQ 3.0L RB30 PETROL WAGON

The most common upgrade for any 3.0L GQ Patrol owner, is the fitment of a 2.5″ Manta exhaust system. The 3.0L naturally aspirated RB30 motor in the GQ Patrol was introduced in 1990, and continued on until the end of the GQ in 1997.

\nAn inline 6 cylinder petrol motor, the RB30 did not have a large amount of power and torque, therefore many owners look for ways to improve the performance and economy of the vehicle. An easy way to improve the performance and sound of the vehicle, is to fit a Manta 2.5″ exhaust.

\nThis mandrel bent, high flow system simply replaces the last two sections of the standard exhaust system to give you better sound, and much more flow. This leads to increased performance, as the engine is able to operate much more efficiently.
