Part # 853072 - Workhorse 8.1L Performance Mufflers
This is a replacement muffler for the Workhorse mufflers, 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 a 10-15 horsepower increase with these mufflers installed when tested on the chassis dyno.
A popular choice for most customers is to install these mufflers along with a set of Banks TorqueTube headers. This will give you the peformance that the headers provide and still leave you with true dual exhaust all the way back, without leaving the restrictive factory mufflers in place. With this combination we see about 30 horsepower and 40 ft. lbs. torque increase.
