Corsa Dodge Diesel 5.9L Muffler

SKU: 8004002 / UPC: 847466005237

Corsa Dodge Diesel 5.9L Muffler Direct-Fit Upgrade for Ram Cummins Trucks

The Corsa muffler is engineered to deliver clear, aggressive sound during acceleration while keeping highway drives free of drone. This 4-inch stainless steel unit replaces stock restrictions with straight-through flow that supports stronger engine output and fuel efficiency compared to factory setups or basic aftermarket options. Drivers choose it for the precise tuning that matches Cummins power curves, providing noticeable gains in throttle response without the resonance issues common in cheaper replacements.

Built from 304 stainless steel for lasting corrosion resistance, the Corsa 8004002 stands out by using patented Reflective Sound Cancellation technology to target and cancel low-frequency vibrations—resulting in a refined tone that outperforms generic mufflers in real-world testing. It’s the go-to for Ram owners seeking a balance of power and comfort, backed by a limited lifetime warranty that covers defects as long as you own the vehicle.
