    FREQUENTLY ASKED QUESTIONS

    This system is designed specifically for the 75 and 78 Series with the 4.2L 1HZ engine. One important note: it will NOT suit the HZJ79 with coil front suspension, as that chassis is different. If you are on a 75 or 78 Series 1HZ you are in the right place, and if you are unsure which model or engine you have, send us your details and we will confirm before you buy.

    It is built to be a refined upgrade, not a boomy race exhaust. The straight-through muffler improves flow while keeping the tone manageable, so it is designed to suit daily driving, touring and light off-road duty without droning on the highway. You get a stronger, cleaner note than stock without living with constant cabin drone.

    It is a bolt-on upgrade to the existing 1HZ layout. The system uses OE-style hanger brackets so it sits like factory, and it comes with the exhaust mounts and gaskets you need for a straightforward replacement. A confident home mechanic can tackle it, and any exhaust shop will have it on quickly.

    You get a 2.5 inch intermediate and tail pipe assembly with a straight-through muffler, made in Australia using mandrel-bent tubing for smooth flow. It is finished with heat-proof paint for corrosion and heat resistance, and it is backed by a 2-year warranty, so it is designed to handle regular driving and touring.

    That is the whole idea. The larger 2.5 inch tubing and straight-through muffler reduce restriction and improve exhaust flow compared to the stock system, which is designed to give you a more responsive feel. It is a practical upgrade for owners wanting better breathing without major modifications to the truck.
