Corvette Headers
Corvette Muscle Car C5 LS1 Coupe Convertible Hard Top
A definitive part of being a muscle or sports car is the exhaust tone that they produce. Corvettes are no exception to this rule and have their own distinct tone, different from mustangs and lamborghinis and everything in between. The purpose of the page is to describe the components that create the exhaust system, and in doing so what each part of the system does and also to explain the overall importance of the dynamics that create the exhaust tone you love to hear when you mash that go pedal to the ground and unleash the power of your corvette.
Corvettes are not unlike any other car when it comes to the basics. This means that the Corvette runs a similar exhaust layout to other cars, consisting of an exhaust manifold, crossover pipe and a cat-back or axle-back exhaust system from the factory. Below these are broken down into their respective sections, and remember that the function of the exhaust system is to guide exhaust gases from the car as quickly as possible. So, without further ado let's talk some shop.
- From the factory all Corvettes come with an exhaust manifold that bolts to the cylinder heads and takes the exhaust gases away from the motor. Most aftermarket replacements are known as shortie and long-tube headers. The difference between an exhaust manifold and headers is in the design. Headers give each cylinder of the motor its own exhaust port to release the gases which are then joined in the collector, while a manifold has multiple cylinders sharing a larger collector.
- On the surface this seems like the manifold would create more power because it has a larger port, but this actually creates excess backpressure and hinders performance.
- A good way to think about backpressure is as a form of turbulence in the exhaust pipes where the gases get turned in the wrong direction and hinder other gases from escaping.
