Not sure if this is the right forum, but anyhow after waiting a ******* month for my header to get here from spd I finally decide to put it on lastnight. I start this thing about 6:30 after a s*** ass day at work get all the rusty bulls*** off of the car and install the CEL fix, so I'm thinking o.k. got the hardest part done the rest will be cake,slide the header into place get under the car while my wife is up top holding everything still and I tell her to push the header back so I can connect where the two springs are at. Low and fuckihng behold it's 2 inches to short (**** this s***) I'm yelling under the car tools are flyin so I crawl back out to take a look at top of the header,warped flange,egr tube does not line up,and my biggest concern is the O2 sensor,I've got the stock exhaust manifold back on now but will having the CEL fix installed already on the O2 sensor hurt anything since I now have both convertors back in place? and I called discount auto to get a price on a new 02 sensor just in case I can't use the one with the cel fix on it ($288 ******* dollars) wtf!(bang)
