Quick answer: the model name on your rego papers isn't enough on its own to guarantee a correct-fit exhaust. Two vehicles with the exact same badge — the same Hilux, Patrol or 79 Series LandCruiser — can need two completely different exhaust systems depending on the engine code, cab configuration, model year and whether a DPF is fitted. The good news: checking compatibility properly takes two minutes, and we've laid out exactly what to look for below so you order the right system the first time.
This is one of the most common messages our team gets before a sale, and for good reason — a wrong-fit exhaust means a returned parcel, a delayed fit-up, and a frustrated afternoon under the car. Here's how to get it right before you click buy.
Why "it's a Hilux" (or a Patrol, or a LandCruiser) isn't enough on its own
Most vehicle nameplates in Australia cover a decade or more of production, multiple engines, several cab or body styles, and at least one emissions-equipment change. Every one of those variables can change which exhaust bolts on. The four things that actually determine fitment are:
- Engine code — the same model can be sold with two or three different engines over its life (for example the Hilux's 1KD-FTV vs 1GD-FTV, or the 79 Series' 1HZ, 1HD-T and 1VD-FTV), and each has different exhaust flanges, mounting points and pipe sizing.
- Cab or body configuration — single cab, extra/space cab, dual cab, ute or wagon changes wheelbase and where the exhaust routes and hangs, which changes the system you need.
- Model year / series — manufacturers update mounting points, underbody heat shields and sometimes flange design at a facelift or series change, even without renaming the model.
- DPF or no DPF — if your vehicle has a diesel particulate filter, you need to know whether you're after a DPF-back system (keeps the factory DPF and emissions gear in place) or a turbo-back system (replaces everything from the turbo outlet back). Fitting the wrong type is the single most common compatibility mistake we see.
Get those four details right and fitment is straightforward. Guess, and there's a real chance the system you order won't line up.
A real example: three different 79 Series exhausts, one nameplate
The Toyota LandCruiser 79 Series is a good illustration of how much variation sits under one model name. Depending on cab and engine, you're looking at genuinely different systems, such as our HDJ79 S-Cab ute 3-inch turbo-back, the VDJ79R V8 D-Cab ute 3-inch turbo-back, and the VDJ79R V8 MY17-on 3-inch DPF-back — same badge, three different engines/cabs/emissions setups, three different exhausts. Ordering by "79 Series" alone, without checking which of these you actually have, is exactly where a mismatch happens.
A real example: same Hilux, two valid exhaust choices
It's not just about engine and cab — sometimes there's a genuine choice to make even once you've matched your vehicle correctly. Our N70 Hilux 3.0L D-4D range includes both a 3-inch turbo-back and a 3.5-inch turbo-back for the same vehicle — both correct fits, but suited to slightly different goals (maximum flow for hard touring and towing vs a more street-friendly setup). If you're unsure which of two valid options is right for how you drive, that's exactly the kind of question our team is happy to help with before you order, rather than after.
How to find your exact details in five minutes
- Check your compliance plate. Usually under the bonnet or on the driver's door jamb, it lists your build date, model code and often the engine code.
- Look up your engine code. It's usually stamped on the engine block itself, or listed on your vehicle's build/compliance sticker. A quick search of "[your rego] engine code" or a look through your logbook will also confirm it.
- Confirm cab/body style and drivetrain. Single, extra/space or dual cab; ute, wagon or troop carrier; 4x2 or 4x4 — small differences that can matter for exhaust routing.
- Check whether you have a DPF. If your vehicle is 2016 or newer, it very likely does. Your logbook, a dealer service history, or a look underneath for the distinctive DPF canister will confirm it.
- Match those details against the product listing. Every system on our site is titled with the exact model, engine code, cab type and year range it fits — browse the full range and match your details to the listing before ordering.
What if your exact variant isn't listed?
Some of our systems, particularly for less common variants and older or classic models, are built as made-to-order rather than held as off-the-shelf stock — that's normal for a business that manufactures in-house rather than just importing generic pipe. If you can't find your exact vehicle listed, it doesn't necessarily mean we can't build for it. Get in touch with our team with your compliance plate details and we'll confirm whether we can match or custom-build a system for your specific vehicle before you commit to an order.
Double-check before you order, not after
The single best way to avoid a fitment mismatch is to ask before you buy, not after the box arrives. Send our team your rego, compliance plate photo, or engine/cab details through our contact page and we'll confirm the exact system for your vehicle. It costs nothing, takes a couple of minutes, and removes any guesswork from the process.
Frequently asked questions
Does this exhaust fit my Hilux, Ranger or Patrol?
It depends on the exact engine code, cab configuration, model year and whether your vehicle has a DPF — not just the model name. Check our Hilux, Ranger and Patrol ranges, match the listing details to your compliance plate, or contact us to confirm before you order.
How do I know what series or generation my LandCruiser, Hilux or Patrol is?
Your compliance plate (engine bay or driver's door jamb) lists your build date and model code, which is the most reliable way to identify your exact variant. Your logbook or a dealer service history will also confirm the engine code.
What's the difference between DPF-back and turbo-back fitment?
DPF-back keeps your factory diesel particulate filter and emissions equipment in place and bolts on from that point back — it's the simpler, road-legal option for most daily-driven utes. Turbo-back replaces everything from the turbo outlet rearward, including (where fitted) the DPF, for the biggest flow gain. You need to know which one your vehicle requires before ordering, as the two aren't interchangeable.
What happens if I order the wrong exhaust for my vehicle?
Contact us as soon as possible — most unused, unfitted systems can be exchanged for the correct variant. It's a straightforward fix, but it's slower and more hassle than confirming fitment upfront, which is why we'd always rather double-check with you first.
Can I get an exhaust custom-built if my exact vehicle isn't listed?
Often, yes. Because we manufacture our systems in-house rather than only reselling generic parts, we can build made-to-order systems for less common variants. Get in touch with your vehicle's details and we'll let you know what's possible.
