Parts for truck exhaust and aftertreatment systems
A truck’s exhaust system and aftertreatment system work together to discharge exhaust gases and reduce
harmful emissions. Modern trucks comply with strict Euro emission standards and are therefore equipped with
advanced systems such as diesel particulate filters (DPF), SCR catalytic converters, AdBlue components and
various sensors. If one of these components does not function properly, this can lead to loss of power,
increased fuel consumption, emission faults and vehicle downtime.
At BAS Parts & Tyres, you will find an extensive range of parts for truck exhaust and aftertreatment
systems. From exhaust silencers and exhaust pipes to DPF filters, SCR components, EGR parts, NOx sensors and
exhaust clamps. This helps you keep your truck’s exhaust system in optimal condition.
Which parts are included in the exhaust and aftertreatment system?
A modern exhaust system consists of several components that work together to safely discharge exhaust gases,
reduce noise and minimise harmful substances as much as possible.
Exhaust pipes and connecting parts
Exhaust pipes, bends, couplings and flexible connections transport exhaust gases from the engine to the
various aftertreatment components and ultimately out of the vehicle.
Exhaust silencers
The exhaust silencer reduces engine noise and contributes to quieter and more comfortable truck operation.
Diesel particulate filters (DPF)
The diesel particulate filter captures soot particles from the exhaust gases. During a regeneration process,
these particles are burned off, keeping the filter clean and limiting emissions.
SCR systems and AdBlue components
SCR systems use AdBlue to convert nitrogen oxides (NOx) into harmless nitrogen and water vapour. Components
such as the SCR catalytic converter, AdBlue injector and various pipes play an important role in this process.
EGR components
The EGR system (Exhaust Gas Recirculation) redirects part of the exhaust gases back to the engine to reduce
nitrogen oxide emissions.
Sensors and emission components
Sensors such as NOx sensors, temperature sensors and pressure sensors continuously monitor the operation of
the exhaust system and enable the engine management system to regulate emissions optimally.
Why is a properly functioning exhaust system important?
A properly functioning exhaust and aftertreatment system not only reduces emissions, but also supports
optimal engine performance, lower fuel consumption and reliable truck operation.
- Reduces emissions of harmful substances.
- Supports optimal engine performance.
- Prevents emission faults and warning messages.
- Helps comply with applicable Euro emission standards.
- Extends the service life of the engine and exhaust system.
Common exhaust system problems
Clogged diesel particulate filter
A saturated DPF can cause loss of power, increased fuel consumption and warning messages on the dashboard.
Defective NOx sensor
A defective NOx sensor can transmit incorrect emission values, causing the engine management system to
register faults and potentially limit engine power.
Leaks in the exhaust system
Damaged exhaust pipes, flexible connections or gaskets can lead to excessive noise, loss of power and
incorrect readings from emission sensors.
Problems with the SCR system
Defective AdBlue components or a poorly functioning SCR catalytic converter can result in emission faults,
power limitation and increased AdBlue consumption.

Frequently asked questions about exhaust and aftertreatment system parts
Which parts are included in a truck’s exhaust system?
The exhaust system includes exhaust pipes, exhaust silencers, diesel particulate filters,
SCR components, EGR parts, sensors and various mounting materials.
What does an aftertreatment system do?
The aftertreatment system reduces emissions of harmful substances by using components such as a
diesel particulate filter, SCR catalytic converter and AdBlue system.
How can I recognise problems with the exhaust system?
Common signs include warning messages, loss of power, increased fuel consumption, excessive
noise or a clogged diesel particulate filter.
