Providing the ability to carry large payloads — be it passengers or gear — has always kept the Chevrolet Suburban and GMC Yukon popular with drivers. But that extra space often means extra fuel consumption. To improve the SUVs’ miles-per-gallon rates, many of the 2007 models are outfitted with Active Fuel Management (AFM) cylinder deactivation-equipped engines, and only CORSA Performance high-performance exhaust systems, designed specifically for this line of General Motors vehicles, are capable of maintaining a "tuned" sound, regardless if the vehicle is in four- or eight-cylinder mode.
"When these large vehicles are operating in four-cylinder mode during cylinder deactivation, a traditional packed muffler is going to make the exhaust sound like there’s a lawnmower in the cabin with you," said Jim Browning, Sr., founder and president, CORSA Performance Exhausts. "Only our patented Reflective Sound Cancellation (RSC) technology is capable of handling the variation in sound frequency that accompanies the engine changing from eight- to four-cylinder mode, producing a pleasing note in either engine mode."
CORSA’s new exhaust systems for the Chevrolet Suburban and GMC Yukon XL feature a straight through design coupled with the company’s RSC technology. This combination creates a robust, full-bodied sound while eliminating undesirable low frequencies that cause resonance.
The CORSA Suburban/Yukon XL exhaust systems are specifically designed for the Vortec 5.3L V8 engine (a Vortec 6.0L V8 exhaust system is also available) to provide a 74 percent gain in flow when bench tested against the stock muffler. The result is an additional 14.4 horsepower and 15.3 lbs.-ft. torque.
Both exhaust systems are available in Sport and Touring versions. CORSA’s Sport Edition exhaust offers maximum performance and a truly aggressive exhaust note during hard acceleration while the Touring Edition is suited for enthusiasts who desire improved performance and greatly enhanced sound quality.
Three exit/tip configurations are also available to suit the owner’s preference:
• Single Side Exit with Twin Pro-Series 4.0" tips
• Single Side Exit with Hydroformed Oval tip
• Single Rear Exit with Twin Pro-Series 4.0" tips
Constructed entirely from premium stainless steel, the performance exhaust systems bolt directly to the factory catalytic converter and require no welding. All hardware and installation instructions are included.
Backed by a limited lifetime warranty the new CORSA Performance exhaust system is 50-state emissions legal, does not void the new vehicle warranty and can be purchased direct from CORSA Performance and through select retailers/distributors nationwide.
Focusing on the development of proprietary technology, CORSA Performance employs patented Reflective Sound Cancellation technology in its performance automotive exhaust systems. CORSA’s 100 percent stainless steel cat-back exhausts are specifically tuned to each vehicle to eliminate passenger cabin resonance and to produce just the right sound. CORSA offers performance exhaust systems and accessories for cars, trucks and SUVs.
