just got a new 99 civic ex, im not going to go crazy on it, no engine swap or nething but i do think i should get exhaust and headers. everyone has apex n1, and dc sport headers. i was just woundering is there an exhaust/header that work better with each ohter?? by better i mean hp. what would u guys suggest as a good exhaust and headers as first mods?? o and was the difference between steel and ceramic headers, niether of them are cast so there shouldnt be ne obstruction??
