Product Description

The CORSA Performance 8004002 dB Series Diesel Muffler is engineered for heavy-duty diesel trucks using 4-inch exhaust systems, including Ford Super Duty Power Stroke and select Cummins applications. It is designed to deliver a performance exhaust tone while eliminating unwanted cabin drone through CORSA's patented Reflective Sound Cancellation (RSC) technology.

Built from 304 stainless steel, this muffler provides long-term corrosion resistance and durability in demanding towing and diesel operating conditions. Its straight-through, high-flow design reduces backpressure and supports improved exhaust efficiency while maintaining a refined sound profile during cruising.

With its universal-style configuration, the 8004002 can be installed using clamp-on or weld-in methods depending on the exhaust setup. It is a popular upgrade for diesel truck owners seeking a balance of performance sound, reduced drone, and long-lasting stainless steel construction.
