Remember I'm paying for labor too. Parts are about $1100, for Flowmasters, headers, true dual H-pipe, and cold air intake. This will not add 40 hp. I could buy a '99 or up V6, but I have my car paid off, I have done a lot to it, I don't want to get rid of it. Besides I like the curvy style of the 94-98 Stang a little bit better than the new edge 99-04 styling. Labor costs drive up the price.. I don't have the knowledge, tools, patience or experience needed to install the parts myself, so I'm paying to have someone else do it for me. I figure these modifications I do will be a good starting foundation if I want to do more in the future.
