Corsa dB Series Mufflers

CORSA(r) Performance Exhausts has expanded its diesel offerings and applied their patented drone-busting technology to the newest lineup of high-performance mufflers for diesel applications.

CORSA's dB Series Diesel Mufflers(tm) are made from 100 percent premium stainless steel and can be fitted to all non-DPFequipped Chevrolet Duramax 6.6L, 6.5L and 6.2L trucks, Ford Powerstroke 6.0L and 7.3L trucks and pre-2008 Dodge Cummins 5.9L trucks. The mufflers, which are designed with 4-inch inlets and outlets, are expanded and notched for clamp-on or weld-in installation, according to the company.

The dB Series Diesel Mufflers feature a straight-through, nonrestrictive design and the company's exclusive Reflective Sound Cancellation(tm) (RSC) technology, which delivers a comfortable, drone-free interior cabin at cruising speed while still providing an aggressive sound during acceleration.

"Our latest product offering fulfills the market's request for a no-drone, high-performance diesel muffler to replace factory or aftermarket mufflers," says Jim Browning, Sr., founder and president, CORSA Performance Exhausts. "Plus, it allows CORSA Performance to be a one-stop shop for diesel owners wanting great sound and increased horsepower, whether they prefer our individual dB mufflers or complete cat-back exhaust systems."
dB series Make way for the ONLY muffler that delivers more HP & torque, a great muscle car sound & up to 4 decibel drone reduction in the car - the Corsa dB series! The Corsa dB is designed and acoustically approved for your specific vehicle. Straight through design gives you 7 to 10% more horespower compared to stock, and there is no stainless or wool packing material to blow out.
