2.5" Outback Exhaust System for Nissan Patrol GU Y61 TB45E

Overview

This 2.5″ Outback Exhaust system is designed specifically for the Nissan Patrol GU / Y61 Wagon 4.5L TB45E, petrol, naturally aspirated (10/97-on). It replaces the factory system with a free-flowing mandrel-bent exhaust and a set of matched extractors, improving gas flow, helping the engine breathe more efficiently and delivering a stronger, deeper note.

Manufactured in Australia from 409 stainless steel, this system is built to handle harsh on- and off-road conditions. The extractors are supplied in high-quality mild steel and are tuned to suit the TB45E engine. The complete system uses the original mounting points, so you get a neat, bolt-on upgrade without the need for custom fabrication.

Delivery & Lead Times

Outback Exhausts note that some systems ship in multiple cartons due to freight weight limits. In addition, freight carriers may require a genuine commercial address for business deliveries, not a residential property. Remote-area orders can attract additional charges, and some locations may require collection from a freight depot rather than door-to-door delivery.

International customers can usually have systems air-freighted, however rates vary by region. The manufacturer assesses freight options on a sale-by-sale basis and may quote separately for export orders. PO Boxes are not accepted as a delivery address, and “authority to leave” is generally not recommended due to theft and proof-of-delivery concerns.
