Description

Overview

The 3″ Outback Exhaust Isuzu MU-X 3.0L 4JJ1 turbo back system gives ISUZU MU-X owners stronger performance, tougher construction and a deeper exhaust note. It suits the 3.0L 4JJ1 turbo diesel MU-X wagon built between 2012 and 2016 and replaces the entire factory system from the turbo outlet to the tail. Outback Exhausts builds this system from mandrel-bent 409 stainless steel with high-quality flanges and brackets, and they engineer it as a direct bolt-on upgrade that uses factory mounting points.

Delivery & Lead Times

Outback Exhaust supplies most systems to order, and lead times can shift with stock levels, production demands and freight locations. Some systems ship in multiple cartons due to their size and weight. You must supply a physical street or business address, as couriers cannot deliver to PO boxes. Remote-area surcharges may apply, and authority to leave may not suit some regional deliveries.
