Ok...quoting this from 5 pages ago:

I read through the posts, but nowhere did you explain the modifications needed. What were they? And to talk about the flex issue...wasn't there a difference in length between auto and 5 speed flex pipes back when you ordered this on the orignal Duratecs? IIRC the auto was longer, so if you ordered that from FSWerks when you order your header, that would solve your problem, right?
Sorry if this was talked about in another thread and I missed it, I just wanted to get some clarity.
