The more that is found out about C7 design the more unknowns there is about tuning, control and what new controllers there are which will not be touched by the PCM itself.

Tenneco announced it is supplying key emission control technologies, including electrical valves, for the 2014 Chevrolet Corvette Stingray, one of the most highly anticipated vehicles debuting in 2013.
Considered one of the key performance features of the car, the Corvette’s exhaust system delivers a unique signature sound.
Most notably, the Corvette’s standard exhaust system is the first vehicle to utilize electrical valve technology for sound tuning.

The electric valves are designed to work in concert with the vehicle’s Active Fuel Management (AFM) system, a fuel-saving four-cylinder mode versus eight-cylinder mode.

The valves open and close to control the Corvette’s exhaust sound as it switches between the two engine modes.


In addition to the valves highlighted in the AFM system, the exhaust system features an option which includes two additional electrical valves in the tailpipes, tuned specifically for enhanced sound quality.

These valves remain closed during normal driving conditions and open during harder acceleration, creating lower backpressure, more engine power and most importantly, Corvette’s signature sound.
