High-flow 3″ turbo-back exhaust system for the Holden Colorado 7 2.8L LWN, made from 409 stainless steel with bolt-on fitment and selectable muffled or straight-pipe sound options.
The 3″ Turbo Back Exhaust System (SKU OE1609-S) from Outback Exhausts delivers a performance upgrade for the Holden Colorado 7 2.8L LWN Duramax Turbo Diesel (2012–2016). Outback Exhausts builds this system from premium 409-grade stainless steel and uses full mandrel bends to maximise flow. It suits the wagon/4WD body style and mounts directly to factory points, so installation remains simple and does not require welding or fabrication. This system improves exhaust flow, sharpens throttle response, and enhances sound quality while maintaining the strength needed for Australian conditions.
