Video: everything you need to know about exhaust back pressure
A Type Approved replacement exhaust, CAT or DPF item for a road car or light commercial vehicle will maintain the correct, balanced, back pressure of the original at normal engine speeds.

In a new video, Doug Bentley, head of research and development at Klarius, discusses exhaust back pressure.

Most road vehicle engines require a degree of back pressure in the exhaust system, including the manifold and exhaust pipe components, in order to run efficiently.

Klarius say back pressure is controlled by the design of the entire exhaust system – including diameter, shape and length of the exhaust and any baffles present in the muffler.

Get it wrong and an engine will have reduced power, use more fuel and generally require servicing more often.

Doug said: “Taking time at the design and testing stages, allows us to ensure we make products that not only comply with EU legislation, but also perform comparably to the original unit.

“A Type Approved replacement exhaust, CAT or DPF item for a road car or light commercial vehicle will maintain the correct, balanced, back pressure of the original at normal engine speeds.

“This will then ensure engine efficiency, engine power and emissions levels are all maintained, it will also look after the engine from a wear point of view and prevent warning dash lights appearing and vehicles being stopped or ordered to limp home by the ECU.”
