That is the 4-2-1 header from rksport. You are right about that. I was gonna get that one for my alero, but I had an auto, and it was like $400.00 so I opted for the pacesetter for $200.00. I would get that one for that good of a price.
well my only concern is that there claiming it to be an arospeed header and the pic is of a rksport header. He also claims in his email that it is an arospeed header and that they do make one for the ecotec that there website hasn't been updated in a yr and it will bolt right up they are a arospeed dealer that it will fit the 03-04 ecotec. So if thats true i guess i'll be placing my bid and getting a new header!
