Hey all. I keep getting the precat code even though I've put a new O2 sensor and a new downstream cat in it, and I suppose throwing another header with upstream cat is the only other thing that it could need to cancel out the CEL, so that's what I need. I actually have a Corksport header for it that I bought back in 2005 that I've never installed, would be willing to trade for a stock header with low miles on the precat. Yes, this is the header that had the fitment issues, so you might have some trouble getting it to fit. Otherwise, I'll pay a reasonable amount for one. Contact me at wyattlines at yahoo dot com.
