Specifically designed for the 2021+ Isuzu D-MAX and Mazda BT-50 running the 4JJ3 engine, our 3.5” DPF-back exhaust system is the ultimate in performance, sound, and durability. Expertly handcrafted on the Sunshine Coast using top-quality 304 stainless steel, it’s built to handle the harshest conditions while delivering maximum gains and a signature turbo-diesel tone.
Tested and tuned in-house for a perfect fit, this system ensures lower exhaust gas temperatures (EGTs), quicker turbo spool, and a deep, refined note that’s aggressive outside but quiet and comfortable inside the cabin.
⏱ Lead Time:
All systems are made to order — please allow 1–2 weeks for dispatch.

📌 Warranty & Compliance Notice:
Modifying your vehicle does not automatically void your manufacturer’s warranty. Under Australian Consumer Law, the ACCC states that a warranty can only be voided if the modification directly causes a fault. That said, DPF delete systems are not road legal and are intended strictly for off-road or motorsport use.
