Scania Exhaust & Silencer Fabrication in Malaysia
Scania operators keep their trucks, which is why we see so many of them at year eight or nine, when the silencer has corroded through and the exhaust is finished long before the truck is. We fabricate replacement silencers, stacks and engine pipes from your original part, in Sungai Buloh, Selangor, in 1 to 3 days.
Identify Your Truck
Scania’s Modular System, and Why It Complicates Parts
Scania builds trucks from a modular catalogue. The same chassis can carry a P, G or R cab, at low, normal or high chassis height, with a 9, 13 or 16-litre engine, in 4×2, 6×2, 6×4 or 8×4. Brilliant for the buyer, awkward for anyone ordering a replacement exhaust, because routing depends on the combination rather than the model name.
| Series | Positioning | Typical Malaysian role | Exhaust considerations |
|---|---|---|---|
| P-series | Compact cab, low entry | Distribution, tipper, construction, urban | Often low chassis, underslung silencer with tight clearance |
| G-series | Mid-range cab | Regional and national haulage, general prime mover | Mid-chassis silencer box, the configuration we see most |
| R-series | Premium long-haul cab | Motorway prime mover, container haulage | Larger silencer body, more heat shielding, side or vertical outlet |
| Construction spec | Any cab | Quarry, logging, plantation, earthworks | Raised or vertical stack, reinforced bracketry, heavy vibration |
Common Malaysian designations include the P360, G410 and R450. The R450 produces 450 hp and 2,350 Nm, which tells you something about the thermal and acoustic load its silencer handles. The G410 is the practical middle of the range and turns up in our workshop most often.
None of this matters much once you send us the part. But if you’re describing the truck over WhatsApp first, the cab series plus chassis height plus a photograph gets us most of the way there.
Thirty Years of Pattern
Where Scania Exhaust Systems Actually Fail
After thirty years, the failure pattern on European prime movers is predictable. We rebuild all four, and because we know where the failures happen, we build those areas heavier than the original.
Construction Sector
Vertical Stacks for Tipper and Construction Units
A significant share of Malaysian Scania work isn’t on the highway at all. It’s in quarries, on plantation roads, in logging operations and on earthworks sites, running P and G series tippers.
Those units usually run a vertical stack, and they destroy them: dust, vibration, impact from branches and overhead loading, plus humidity and dust combining into an abrasive paste.
We fabricate complete stack assemblies, from the elbow at the silencer outlet through the vertical section, mounting bracket, heat shielding and rain cap. Reinforced bracketry is standard on construction-spec builds, not an upgrade.
If your site requires a spark arrestor, and plantation, quarry, mining and refinery sites almost always do, we build those too. See our spark arrestors page.

Sabah & Sarawak
East Malaysia, Where a Lot of This Work Is
A large share of Malaysia’s heavy Scania population works in Sabah and Sarawak on palm oil, timber and construction logistics. Those operators are furthest from the dealer network and most exposed to lead time.
If your Scania is throwing backpressure or sensor faults, check the pipework before assuming the emissions system is at fault. Running a mixed European fleet? See our Volvo truck exhaust page, or the full custom exhaust fabrication overview. Thirty years of this work is documented on our about us page.
