Outback Exhausts 2.5-3” Cat-Back System for Toyota LandCruiser 100 Series — stainless steel, bolt-on, mandrel-bent exhaust for improved flow, sound, and performance.
The Outback Exhausts 2.5–3″ Cat-Back Exhaust System is designed for the Toyota LandCruiser 100 Series (4.7L V8 UZJ100, 1998–2007). Constructed from durable 409 stainless steel, it improves exhaust flow, throttle response and overall performance. The system replaces the factory rear section while keeping installation simple through direct bolt-on fitment using the original mounting points. With mandrel-bent tubing and a dual 2.5″ to single 3″ layout, it delivers a deeper exhaust note and increased efficiency suited to towing, touring and off-road driving.
This Australian-made system offers a reliable upgrade over the restrictive factory exhaust and maintains long-term durability in harsh conditions. For customers seeking professional installation, Sunshine Coast Diesel Tuning provides full fitting services and post-install inspections.
