How to Make a Honda Civic Faster
- 1). Purchase an upgraded air intake system--the most important item a Honda Civic owner can purchase to improve performance and increase horsepower. Upgraded air intake systems allow more air to enter the engine. The additional oxygen allows for better combustion, improving the overall performance of your car. A new air intake system can increase the power of a car's engine between 5 hp and 11 hp, according to autosportz.com.
- 2). Purchase an upgraded exhaust pipe. An upgraded exhaust pipe can also improve the speed of a Honda Civic. Exhaust pipes give the exhaust run off from the engine a pathway to escape. Exhaust exits the engine more quickly and allows the engine to burn new fuel more quickly with upgraded systems due to a more direct pipeline and higher quality metals used in the manufacturing process. In short, a better exhaust system allows a Civic's engine to "breath" better which thereby improves performance.
- 3). Purchase exhaust headers to increase the flow of exhaust fumes from the engine of a Civic. Each cylinder on an engine produces its own exhaust fumes. Thus, each cylinder is competing to expel exhaust fumes from the exhaust pipe. Exhaust headers are tantamount to giving each cylinder its own exhaust pipe. Each cylinder can now expel old exhaust fumes freely and without the effects of the other cylinders expelling exhaust fumes. Much like an upgraded exhaust pipe, exhaust headers allow the engine of a Civic to "breath" easier and perform better.
