OUTBACK EXHAUST SYSTEM dump pipe to suit ISUZU DMAX 3.0L 4JJ1 7/12 – 2016

Description

Overview

The Outback Exhaust System dump pipe for the ISUZU DMAX 3.0L 4JJ1 (2012–2016) delivers stronger exhaust flow, lower back-pressure and a noticeable improvement in performance. Outback Exhaust engineers manufacture this pipe in Australia using durable 409 stainless steel, ensuring excellent heat resistance and long-term reliability. It bolts directly to the vehicle and integrates cleanly with the matching Outback Exhaust System, allowing a fast installation without modifications or welding. Mandrel-bent construction keeps the internal diameter consistent, helping the engine breathe more efficiently while enhancing the exhaust note.

Delivery & Lead Times

We ship orders Australia-wide and internationally. Some systems ship in multiple cartons due to weight restrictions. Remote destinations may require depot collection or attract additional freight fees. A physical delivery address is required because exhaust freight cannot be delivered to PO Boxes.
