Alright check it out, I installed it they are OBX headers and I bought them at OBX... The car was getting the emmissions code 0247 or what ever and I put in a mil elimantor and it went away but it was shortly greated with a 0300 (random multiple misfire code) SO I changed the entitre ignition system (coils, wires, plugs), that didnt work so i changed both o2 sensors and reinstalled another mil eliminator, that didnt work so I changed the pcv valve the Maf and the Idle sensors.... And I'm in the process of cleaning the egr valve... SO basically the car starts runs fine for a minute then trips out and jumps all over in the rpms and studders and attempts to stall...
