whats a good cold air intake,header,and exhaust for my 2000 honda civic si?

you should probably stay away from modding hondas becuase:1. their slow2. real sport car enthusiats will laugh at you3. youll only be able to beat or keep up with other hondas4. its a waste of money when you can get a turbo....

AEM intake, DC Sports header, and Greddy EVO2 exhaust.

AEM intake, DC sports 4-2-1 header and I'd go Skunk2 Exhaust, if your SI has the factory B16 they I'd go with 2 1/2" piping all the way back and you'll get a nive healthy rumble at low speeds and a solid tone when your V-tec kicks in.

Well if ur car has the b16 which im pretty sure it does u would probably have 160 hp and 113 ft/lb which isnt really a lot so if u get those boltons u wouldnt really get much more power but u would feel a difference in power. For the Intake get either the AEM cold air intake or the AEM short ram intake depending if ur willing to take off ur front bumper or not because for the AEM cold air intake u have to take off the front bumper to install it but for the AEM short ram intake u dont...anyways there isnt much of a difference to either one other than that youll have a different throttle response from the short ram intake. By throttle response meaning that feeling u get on ur foot when pressing the gas pedal. FOr the header u can either get a comptech header because they make one of the best headers BUT theyre really hard to find and they're expensive. The other good headers u can get for cheap but are good are the DC sports 4-1 header or the DC sports 4-2-1 header. The 4-1 header basicly increases top end power and the 4-2-1 header increases low to mid range power but there has been debates on whether its tottally true or not. and for the exhaust it depends on if u like it quieter or louder but since i like the quiet type im gonna tell u the quieter kind. U should get either the Greddy EVO2 but the muffler is like a huge canister.(its REALLY big but at the same time pretty quiet) or u can get the Apexi world sport2 exhaust because its also really quiet and the muffler is slightly bigger than stock. HAve fun!
