Corsa RSC Cat Back Cummins Exhaust System

Dodge Cummins with Corsa exhaust system
Whether you're towing your trailer or taking a Sunday drive, you want the best sound, looks and performance from your Diesel truck. CORSA Performance exhaust systems offer great performance sound and enhance the look of your vehicle, while increasing horsepower and torque for towing. And thanks to our patented Reflective Sound Cancellation™ (RSC™) technology, we do it all without annoying interior resonance. All systems are 100% stainless steel and come with a lifetime warranty. So enjoy your truck everyday on the way to work or play!! Using the patented* Power-Pulse RSC™ technology found in our top-selling exhaust systems for trucks and suv's, we have developed a new line of powerful diesel systems offering equally impressive power and sound quality improvements. The proprietary mufflers provide a rich acceleration sound in character with the system's free-flowing nature, while Reflective Sound Cancellation technology uses exhaust sound waves against one another to create a quiet note at cruising speeds. All system components are meticulously crafted from stainless steel for long life and performance that will never "burn out," and computerized mandrel bending assures perfect fit and easy installation. Premium CORSA Performance Diesel Truck Exhaust Systems carry a Limited Lifetime Warranty!!

CORSA combines three design features into its 100% stainless steel exhaust systems that no other aftermarket manufacturer can match:
1. No Resonance/Drone: Due to our patented Reflective Sound Cancellation (RSC™) technology, your exhaust is whisper quiet at highway speeds.
2. Increased Horsepower and Torque: Resulting from a straight-through design. Produces increased flow and less back-pressure.
3. Great Performance Sound: We tune in the good sounds and cancel the bad, without the use of baffles or steel wool packing material.
