b16a into a 98 civic etc etc etc... ok, picture this..... you get through the wiring nightmare of the OBD1 engine - OBD2 chassy you get everything put in without too much trouble you realize that you only have the exhaust manifold and not the downpipe. yes, i completely forgot to get a header i know...im a dumbass a friend of mine has a header off of a 95 integra GSR...will everything fit right? he lives in DC, so i can't exactly put the header up to the car before i buy it...if it fits right ill only have to pay $30 for it.... so will it fit right? i.e. will it be long enough to bolt to my cat-back thats already on there? or am i gonna have to buy an si header?
