An exhaust system is a complex system of components which perform a series of critical emissions functions.

Commercial vehicle manufacturers continue to develop more effective emissions controls for diesel vehicles to meet the required reductions in emissions levels.

The exhaust system is one of the very few parts on a vehicle that continues to wear even though the engine is not running and the vehicle is stopped.

Many factors mandate exhaust system replacement to control harmful emissions and maintain safe vehicle operation.

A properly functioning exhaust system can improve your bottom line.
