ok so i just got a 2004 honda s2000 and i am planing on doing some modifications my self to it but i need help on what to do. i am not made of money so i am trying to keep it cheap so i was doing to start out with a air-intake and a good exhaust. first what are some good air intakes and exhausts. i have been thinking about a k&n air-intake and maybe some kind of f1 exhaust but i want one that adds some power. after doing all of that what would be some good upgrades that would not brake the bank. plz help me out
