Enhancing horsepower and torque of a car is beneficial. Modifying the exhaust system of Honda civic car is the most economical way to do so. The exhaust system consists of many components including Honda civic header i.e. exhaust manifold, a down pipe or outlet, catalytic converter, muffler and exhaust tilt. The major concern is piping and the type of muffler used in the case of Honda civic exhaust system.

Numerous options are there while selecting the components of Honda civic cat back exhaust system. Quite a lot of exhaust system manufacturers are there in the market. The main work is to research on the type of exhaust system you want for your Honda civic car and then buy it form the dealer. Each system has its own pros and cons.

It is necessary to improve your Honda civic cat back exhaust system. This can be explained by an example-the exhaust escape velocity and exhaust flow capacity are the two major factors that are taken in account. Consider a system of water hose to get an idea of exhaust system. If a spray nozzle is detached the velocity with which water comes out is less but the volume is more. While when the spray nozzle is attached the water will come out at greater velocity but the volume of water is less. To get maximum power from your Honda civic cat back exhaust system the best way is to find a balance between the flow volume and velocity. Hence the size of the pipe in the exhaust system plays a vital role.

A four cylinder power engine is used foe power production in Honda civic car. Thus 2.25 inches of pipe is sufficient for normal power production i.e. when there no further induction. However if the larger diameter pipe is used there is decrease in bottom end power production. It is similar to detaching of the nozzle in case of water hose. Low velocity but larger exhaust flow.

The total power gained also depends on the type of muffler used in Honda civic cat back exhaust system. A glass pack which is like a cylinder stuffed with fiberglass is used to reduce the noise. This is type of muffler have disadvantage of being extremely loud though it has excellent flow capacity. A choice of no mufflers is also not suitable because by that the noise would be so loud that it will be unbearable.
