2.5” OUTBACK EXHAUST SYSTEM to suit TOYOTA HILUX LN 172 3.0L 5L-E NATURALLY ASPIRATED 1997 – 02/05 (WITH EXTRACTOR)

Description

Overview

This Australian-made 2.5-inch exhaust system is engineered specifically for the Toyota Hilux LN172 3.0L 5L-E (1997–2005). Built using mandrel-bent 409 stainless steel, it delivers improved exhaust flow, stronger mid-range torque, and a deeper, more refined exhaust note. The system replaces the factory components and includes a set of extractors, all major pipe sections, and a complete fitting kit. Installation uses original mounting points for a straightforward bolt-on fit.

Designed for touring, work use, and daily driving, the system offers durability and reliability in harsh Australian conditions. It is suitable for Dual Cab models and can also fit Extra Cab models using the included weld-on extension sections. For more product details, visit Outback Exhausts. Installation and support are available through Sunshine Coast Diesel Tuning.
