I think I have wasted enough money now. I now have two headers that dont do the trick. Most know that with a B18C1 in an EG Civic that there will be about a 6 inch gap between the end of the header (collector) and the cat. In my hopes of not having to weld anything I went on researching for a header that would span the gap. 1st bit of advise had me buy a Type R header (aftermarket). It looked like it would work so I bought it. Well it wasnt quite right. The 2.5" collector doesnt fit well with a stock cat. And for some reason its alignment doest quite mesh since it tweaks my B-pipe to the passenger side about 2-3 inches. Its what I am running right now but it needs to be swapped for something better. Numero 2, I was advised to get a B18B (LS, RS) header. That came in on Friday and before I took my existing header off I mocked it up and found a couple glaring problems. It seems to be a little short and the collector flange will not line up. So what do I do. There has to be a header out there that will work for this common swap. I really want to avoid the muffler shop.
