[VIDEO] Inside the Development of CORSA’s C7 Corvette Exhaust Systems

Corsa exhaust systems have found their way onto countless C5 and C6 Corvettes.

Now the aftermarket exhaust manufacturer has unveiled its latest system for the C7 Corvette. It sounds great, offers a big increase in performance, and even offers customization not previously offered.

In this video, Corsa officials explain the process behind its new systems for the Stingray, and you’ll see, it definitely wasn’t easy.

Brent Noward, marketing manager, says Corsa had a three-pronged goal for its system.

“We needed to create an aggressive exhaust note that perfectly matches up to the C7’s aggressive styling,” he explains. “We had to produce a high-performance exhaust system that flows freely and outperforms the stock systems to unlock additional horsepower and torque from the C7’s engine. And of course we had to deliver a system that does not drone … the way our customers expect.”

Noward says Corsa has spent more than eight months of research and development and over 1,000 manhours of engineering and design time and hundreds of hours of testing to come up with its new system. Corsa engineer Dave Niksa notes that the C7 exhaust system has been the “most complex” to develop in the company’s history.

“The C7 with its wide range of newly advanced technologies forced Corsa to deliver a range of solutions that works perfectly in harmony with these technologies,” Niksa says. “Producing an exhaust system that delivers more flow and the proper sound in all Corvette driving modes, including four-cylinder eco mode, took additional development and engineering expertise.”

Through a series of creative solutions and multiple alliterations, Niksa says, Corsa’s C7 valveback design utilizes the best of General Motors’ technology with the latest developments in Corsa’s acoustics engineering to deliver “the ultimate C7 Corvette exhaust solution.”

Hundreds of hours of testing, including the evaluation of the removal of the upstream axle pipe valves from the stock Corvette exhaust system, showed that there was no significant difference with the removal of these valves, Niksa says.

Final testing confirmed only a minute horsepower difference between the valved and non-valved axle pipe designs, but the valved design would have required a significant price increase to the customer to incorporate components Corsa felt are unnecessary, he says.

But cutting to the chase, the new Corsa system when equipped with its all-new Double Helixx X-pipe design adds up to 20 horsepower and 15 lb-ft of torque over the stock exhaust system.

Also, the new system offers a choice of clamp-on tip designs so that customers can customize their system to their preference.

And of course, the sound is out of this world. Just listen to the end of this video for proof.
