An after-market assembly designed to replace or upgrade the factory-installed emission system on a specific model of heavy-duty truck, specifically the Kenworth W900L. These kits typically include components like mufflers, pipes, clamps, and mounting hardware. As an example, a driver might choose this assembly to improve engine performance or achieve a desired aesthetic.
The selection of such a system can significantly impact a vehicle’s fuel efficiency, power output, and overall sound profile. Historically, these components were primarily focused on functionality, but increasingly, owners seek options that combine performance enhancements with a distinctive visual appeal. The availability of diverse materials and designs reflects this evolution.
