I own a 1993 Honda Accord and I want to spruce it up, not just be plain show and all ricey. But I have heard that when starting out, there are several mods you can perform to increase the HP a little. Some people say a good intake and a good exhaust, a combination of both can increase about 10-20HP (could be a lie, you know how some people exaggerate, havent seen many dyno shots). But so far I have a stock everything engine-wise Where should I start to slowly build my horsepower up?
