Got the stock manifold out. I noticed another nut that I missed further down, it looks like just an extra mounting bracket that it was bolted to.....that was a pain because of location. Anyway I pieced together the megan racing header, looks nice. Looks like there is an extra hole for another o2 sensor near the end. For earlier model civics maybe?

Got the header on last night didn't take long after getting the manifold off. Test drove it right after around 9:30,no cel light, or problems which felt really good. Just with that one b00shing in, the whole feel of the shift is stiffer, not loose at all. I like it a lot lol.
Header alreadychanged to a bronze colorafter I drove it around today. The firsttest runI just let it idle forlike 20 minand was cautious when i drove it a short distance. Today after it warmed up to good operating temp, I opened her upall the wayon the highway. Very nice header. can def feel a difference even top end power.
There was one nut that wasn't on the header, i dunno if I forgot to put it on or if it came off but lol. Didn't seem to be too much of an issue. I retightened all the nuts on it and I think in a few days to a week I'll get under it and see if anything needs tightening after it breaks in a little more.

Thanks for all the help guys!!!!

extra?! that should be the one that you use. where is your primary oxygen sensor now??

 

It's closer to the engine block, around where it was put into the stock manifold. There's one there and one behind the cat-converter (look in the other pic with the bronze color to it, you'll see it faintly)
