3” OUTBACK EXHAUST SYSTEM to suit NISSAN PATROL GQ WAGON 4.2L TD42 04/91 – 10/94 (TURBO BACK)

Description

Overview

The 3″ Outback Exhaust Nissan Patrol GQ TD42 Turbo Back system is engineered specifically for the Nissan Patrol GQ wagon 4.2L TD42 diesel built from 04/1991 to 10/1994. This Australian-made system replaces the factory exhaust from the turbo outlet right through to the tailpipe. It improves exhaust flow, sharpens throttle response and delivers a tougher note. Outback Exhausts builds this system from durable 409 stainless steel, and the kit bolts directly to vehicles running the GU manifold and turbo. It suits touring, towing and off-road work thanks to its reliability and heat resistance.

Outback Exhausts manufactures every system in Australia using mandrel-bent tubing, reinforced hangers and OEM-style flanges. This approach ensures consistent fitment, strong durability and a clean, professional finish. You can select from several sound options at checkout—large muffler, resonator/small muffler or straight pipe—to match your preferred note and comfort level.
