High-quality exhaust pipes for efficient emission control

A perfectly tuned exhaust system starts with the right exhaust pipe. In the heavy-duty use of trucks and commercial vehicles, these pipes have to withstand extreme temperatures of over 600°C and aggressive exhaust gases. Our exhaust pipes are made from high-strength aluminized steels or stainless steel to provide maximum corrosion resistance against road salt and moisture. A smooth internal flow also minimizes exhaust back pressure, which optimizes engine performance and sustainably reduces fuel consumption.

Flexible pipes and connecting pipes for long-lasting exhaust systems

Enormous dynamic forces act within the exhaust system. The connection between the engine and the permanently mounted silencer in particular requires flexible solutions. In addition to the classic exhaust pipe, FZB offers heavy-duty flexible pipes that reliably compensate for engine vibrations and thermal expansion. This prevents cracks from forming on expensive components such as the turbocharger or particulate filter. Rely on custom-fit connecting pipes and tailpipes in OEM quality to extend the maintenance intervals of your fleet.

Exhaust pipe

What should you look out for when buying:

PRECISE FIT

Match the original spare part number (OE number) with your truck model (e.g. MAN TGL, DAF XF).

HEAT-RESISTANT MATERIAL

Only aluminized steel or stainless steel offer the necessary protection against heat and corrosion.

FUNCTIONAL FLEXIBILITY

In the case of flexible pipes and corrugated pipes, ensure a reinforced design in order to optimally compensate for vibrations.

Thermal and mechanical extremes in the truck exhaust tract
The exhaust pipes of a truck are exposed to extreme conditions that far exceed what is usual in a passenger car. The massive diesel engines generate high exhaust gas temperatures, which reach peak values particularly in the vicinity of the turbos and exhaust gas aftertreatment (DPF/SCR). In addition, there are high mechanical loads due to permanent vibrations of the chassis and the engine as well as the torsion of the body. For this reason, truck exhaust pipes must have superior heat resistance and corrosion resistance (especially against aggressive condensates from combustion and AdBlue residues). Failure of a pipe can massively increase noise development and jeopardize the operating license.

Critical connection to the emissions control system
In modern trucks, exhaust pipes are not just simple pipes, but precisely manufactured components that are integrated into the complex emissions system. The pipes are directly connected to the particulate filter (DPF) and the SCR catalytic converter. The absolute tightness of these connections is crucial: leaks would lead to the release of unfiltered exhaust gases and interfere with the sensors (pressure, temperature, NOx) in the system, which can lead to error messages and a reduction in engine performance (emergency running program). The precise fit of each pipe flange and the quality of the retaining clamps are therefore essential for the correct functioning of the entire Euro standard system.

Economic efficiency through remanufacturing and material selection
Due to the high costs associated with replacing solid exhaust pipes and the sustainability aspect, the use of remanufactured exhaust components is also becoming increasingly important in the truck sector. Regardless of whether it is a new or remanufactured part, the longevity of the exhaust system depends on the choice of material. Stainless steel or highly aluminized steel offers the necessary resistance to external corrosion caused by road salt and moisture as well as internal corrosion caused by exhaust gas condensates. Investing in tested, heat-resistant components minimizes the risk of unscheduled workshop visits and ensures the cost-effectiveness of the truck fleet.

Expert guide: Everything about truck exhaust pipes & exhaust technology

Aluminized steel and stainless steel are ideal for commercial vehicles. These offer the best compromise between heat resistance, weight and protection against corrosion caused by weathering.

Leaks not only cause noise pollution, but can also conduct hot gases to sensitive lines or trigger error messages in the sensor system (lambda sensor).

Typical signs are traces of soot at the joints, loud exhaust noises, rattling while driving or visible rust through.

It acts as a decoupling element. It absorbs the movements of the engine so that these are not transferred rigidly to the rest of the exhaust pipe, which would prevent breakages.

Dents or constrictions increase the back pressure. This leads to an additional thermal load on the engine, loss of power and increased diesel consumption.

Euro 6 systems work at very high temperatures to regenerate the particulate filter. Specially alloyed pipes are often used here, which can withstand these heat cycles without material fatigue.

The use of high-quality pipe clamps and intact rubber buffers is essential. Stress-free installation prevents the exhaust pipe from tearing under load.

In many modern trucks, tailpipes are aerodynamically shaped to direct exhaust gases away from the bodywork or trailer. The wrong pipe can lead to soiling or heat build-up.
