Aftermarket Euro IV & V Truck & Bus Silencers

Did you know Northern Mufflers is now able to supply a range of aftermarket silencers for trucks and buses with Euro 4 & 5 compliance?

Our Flowtech range of silencers can help you save $$$ on expensive genuine parts. We offer the following options:


We can organise to have your faulty silencer picked up and sent to our manufacturer. The silencer is opened up, inspected, cleaned and then repaired if possible. A cost-effective option worth investigating if time permits.


If time is critical, we have access to a range of reconditioned genuine parts, for certain models.

New - OEM Alternative

Flowtech aftermarket silencers are built to the same specifications as genuine but at a better price. Off the shelf, direct fit replacement silencers are available on many models - for makes including BCI, DAF, Kenworth, Mack, Mercedes, MAN and Volvo.

Below are the current product listings we have. Bear in mind not all models are stocked, and if your model is not listed, please call for further details:
