I have an 03 Protege ES and I bought a cheap ebay header for it just to clean up the engine bay. I dropped it off to the guy that alway does all of my exhaust work while I was out of town yesterday and a couple of hours later I got a call saying that the EGR wouldn't hook up and that the header was against the oil pan. Both of these are common problems that I have heard before. I was just wondering what you guys thought I should do to fix this. I have heard some people say that they just put a filter on the EGR or just hook it up then bolt up the header. Will I have a CEL if I just put a filter on the EGR line? Can I pull the entire EGR line and put the filter closer to the intake so I don't have a line with a filter just hanging out? Is there any cheap headers that I won't have all of these issues? Any help would be great. I am wanting to get some input before I decide to just ship this one back.
