The exhaust system is usually hidden unless the car owner opts for shiny chrome exhaust tips but the tubing system is essential for guiding reaction gasses away from the engine and keeping the engine cool and the driver and passenger safe from noxious gasses. Some muffler and exhaust systems are specially designed to increase the engine horsepower and to do that many Corvette owners will opt to swap out an OEM exhaust for a higher performance system.
There are several high quality exhaust system manufacturers that design mufflers, tips, tubes and exhaust parts that fit perfect with Chevy Corvettes including Edelbrock, Dynatech, JBA Headers and Corsa. Unlike brakes and transmissions that require genuine Corvette parts to function properly the exhaust system aftermarket is full of high quality, high performance exhaust systems and parts that can be used on a wide variety of car makes and models and will improve the horsepower and torque of almost any make or model of Chevy Corvette.
Other interesting features in the overall layout of the engine included moving the engine 1" forward. 1"? What could that do? Actually, it allowed for a better exhaust system, which in turn gave the car more power. There is more than enough power to exceed the traction of the rear tires. But cornering also had to be considered in the engine design. If the car is capable of 1.0+ G's in maximum cornering, this is the equivalent of turning the engine on its side at 45 degrees. The team made a different windage tray and oil pickup to control the lubrication system during spirited driving. Redesigning also allowed the team to eliminate the "gull-wing" oil pan of older models leaving room for more exhaust work to further tune the engine.
But how did all of these modifications effect the overall gas consumption? The new Corvette can get 23 mpg on the combined EPA city/highway test. That's better than the 320 hp Porsche 911 at 20 mpg. Forget the 400 hp Ferrari Modena at 12 mpg.
This new engine has been totally redesigned for the Corvette enthusiast and shows a tremendous effort GM has put forth for this new model. This is by far the best Corvette ever produced.
