Default 1998 Honda Civic EX Coupe modify?

aright so recently bought a 98 honda civic ex.















now im looking into buying an intake injen, a throttle body, and new headers.















i want this baby to go pretty fast but not fast where i cant even control it, just decently fast, if that makes sense.















Are there any certain types of intakes, throttle bodies, and headers that you recommend, along with the website?















i dont have that much knowledge on the different types.















another thing, whats the range on how much it would cost to get the headers installed? i can install the intake and throttle body because ive done it before with a friend, but i dont really want to install the header because i hear its a complete pain.















thank you very much!















another thing! one of my friends said i should get a new exhaust, he said something about changing the whole thing. what does that mean? and could you let me know of a good exhaust to get? thank you!

don't think about a header if you live in California. the police there will ticket you for noise pollution















also headers do warp since their not cast iron. The cheapest way to increase horsepower would be to increase the timing but you will be using premium gas from now on. Headers alone only increase horse power by about 5 unless you add a thrush muffler. if you don't use a thrush muffler headers will be self defeating but the police will be watching you. For every day street use leave it alone. if you want a fast Japanese car thats stock trade it in for a Mazda rotary

In all honesty, it takes A LOT to make a Civic decently quick, and if it's an automatic you might as well throw the towel in now.















But of course it's your car so you can throw on the throttle body, header, intake, and an exhaust system if you want and if your lucky you might gain 15whp from all that, and by then just those put you in the hole about $1,500.































Now about the header and exhaust.















The above answer isn't necessarily true if you live in California. In California any modification parts require what's known as a CARB stamp (or E.O. number). These stamps provide proof that the part is street legal in the state. Nearly all good brand name parts have this stamp, most of the cheap eBay stuff does not and is therefore illegal in CA.















Secondly, a header is actually quite simple to do. Once the front of the car is situated on jack stands all you gotta do is break the bolts loose and drop the header down then install the new one. Some headers may require some wire work to extend the oxygen sensor line, but not all. Parts stores also have an option for oxygen sensors with longer wires so wire work may be avoidable.































Your friends reference to changing the whole exhaust is a smart idea. Most people with Honda's just go to Pepboys or some other crap store and buy an annoyingly loud $60 muffler that provides no benefit at all except tons of useless loud noise. By the "whole thing" he means changing out everything on the exhaust system from the end of the catalytic converter all the way back a.k.a. Cat-back Exhaust Systems.















If you don't know what exhaust system to get, check out these videos of a bunch. http://honda-tech.com/showthread.php?t=2035530















Find the one with a sound you like and Google it to see who's selling that type.

i would say definently get the intake system and headers. personally i would recommend the Skunk2 or Megan Racing brand name for headers. but getting heades will do nothing without a full exhaust system. your headers will be just as resrictive as your old ones if you do not replace the whole exhaust. so if you go headers, then go exhaust too. their are many exhaust systems i would go will, perferrably Skunk2, Megan Racing, Greddy, and Mugen. out of these Megan Racing would be my choice because they make quality parts and a system for your car is well priced. a Skunk2 intake manifold would also be a very wise mod that you could do, it is much less restricting than the stock intake manifold and will put much more air into the engine along with the intake system
