Just got dune readying the artical in mm&ff about the fr500 exaust it seams like a sweet system. Accourding to MM&FF it will be available to buy through ford racing.( correct me if i am wrong) anyone have a clue on the cost of the nice set up. 8-10 hp at the wheels is nice for a cat system on a stock stang. if you havent read the artical yet do so its pretty good.
