Description

Overview

The 2.5″ Exhaust Cat-Back from Outback Exhausts replaces the factory system on a Nissan Patrol GU Y61 with the 4.5 L TB45E petrol engine (Wagon model, 1997-on). Outback Exhausts manufactures this system in Australia using OEM-grade 409 stainless steel for strength and long-term reliability. It improves exhaust flow, delivers a deeper exhaust note, and offers dependable performance for touring, towing or daily driving. The kit mounts to the original points, requires no welding, and usually installs easily without the need for a hoist.
