WALKER® COMMERCIAL VEHICLE: Reasons to Require Exhaust System Replacement
A thorough inspection identifies components which are near the end of their useful service life. It also could identify exhaust leaks, which could lead to harmful emissions entering the cab of the vehicle. Replacement of worn components eliminates the potential for in service failures and maintain vehicle safety. Other benefits of replacing worn exhaust system components are:

IMPROVED FUEL ECONOMY
  • Modern commercial vehicle powertrains are more technologically advanced than powertrains of even just a few years ago
  • Many utilize sensors which rely on tight exhaust sealing for accurate monitoring of the combustion process
  • Older powertrains rely on tight sealing of exhaust components for engine efficiency
  • Excessive back pressure to due to failing exhaust components, such as mufflers, can lead to reduced engine efficiency and reduced fuel economy

REDUCTION OF HARMFUL EMISSIONS
  • Exhaust leaks can lead to cylinder imbalance issues which is one of the main reasons of elevated emissions

EXAMPLES OF WEAR DEFECTS REQUIRING VEHICLE EXHAUST SYSTEM REPLACEMENT INCLUDE:
  • Leaking pipe / elbow / flex
  • Corrosion hole(s)
  • Broken or missing mounting component(s)
  • Rattling or knocking noise from exhaust
