Turbo Back Exhaust – Mitsubishi Triton MK 2.8L 4M40 (1996-2006) | Outback Exhausts

Overview

The Outback Exhausts 3″ Turbo Back Exhaust System delivers a strong performance upgrade for the Mitsubishi Triton MK 2.8L 4M40 (1996–2006). Outback Exhausts manufactures this system in Australia using durable 409-grade stainless steel, ensuring long-term strength and resistance to harsh conditions. Its free-flowing, mandrel-bent 3″ design replaces the restrictive factory system and improves exhaust velocity, turbo response and mid-range power. Drivers also gain a deeper, more refined exhaust note.

This bolt-on system mounts directly to the factory points, so installers do not need to weld or modify components. Its design supports owners who want reliable performance during off-road driving, towing or touring while keeping installation simple and efficient.
