853072 - Workhorse 8.1L Performance Muffler

This is a replacement muffler for the Workhorse W-Series muffler, minus the factory flanges and hangers which should be reused. These mufflers also flow much more than the factory mufflers so you will want to install them as a set. These mufflers have proven to increase performance and extract exhaust heat from the engine. These gains are also achieved while still retaining the factory mellow sound. We have seen on average between 5-10 horsepower increase with these mufflers installed when tested on the chassis dyno.
