Tenneco's Emissions Control Sytems Provide the 2014 Corvette Stingray's signature Sound

Just about everything about the upcoming 2014 Corvette Stingray seems to be preceded by the word “first.”

Now here’s yet another part of the seventh generation Corvette that’s leading the way for other cars.

The Corvette’s standard exhaust system will be the first vehicle to use Tenneco’s electrical valve technology for sound tuning to provide a unique signature sound when you drive this exciting beast.

The electric valves will be working together with the vehicle’s new Active Fuel Management system, which saves gas by switching between four-cylinder and eight-cylinder mode. As the Corvette switches between the two engine modes, the valves will open and close to control the sound of the exhaust.

In addition to those valves, the exhaust system will also include the option of two more electrical valves in the tailpipes, tuned specifically for enhanced sound quality. During normal driving conditions, these extra valves will be closed, but they’ll open during harder acceleration, creating lower backpressure, more engine power, and that beautiful Corvette signature sound.

“The Corvette is one of America’s iconic automobiles, and Tenneco could not be more excited and pleased to partner with Chevrolet to provide a combination of performance attributes, including improved fuel economy, power and the vehicle’s signature sound,” said Tim Jackson, Tenneco’s chief technology officer. “Additionally, the program gives Tenneco an opportunity to demonstrate our advanced exhaust technology on one of the highest performance vehicles available in the market.”

Tenneco supplies ride performance and clean air technologies for GM cars and trucks around the world. The Corvette’s electric valves will be made in Spain, and the other system components will be manufactured in Nebraska and Indiana. Tenneco’s Smithville, Tennessee plant will have the honor of hosting the final assembly of the exhaust system.

Tenneco is a $7.4 billion global manufacturing company with headquarters in Lake Forest, Illinois and approximately 25,000 employees worldwide. Tenneco is one of the world’s largest designers, manufacturers and marketers of clean air and ride performance products and systems for automotive and commercial vehicle original equipment markets and the aftermarket. Tenneco’s principal brand names are Monroe®, Walker®, XNOx™ and Clevite®Elastomer.
