Just realized U had a thread going. I get all my work done at Midas on 347 the owners name is Eddie and works on mustangs all the time. Ur also gunna need mile eiliminators that u can get off of American muscle. This will keep the check engin light off. My bad dident realize u had a Mach 1 with 4v. Good luck
Thanks , Yes I do live in setauket. My set up is bbk o/r xpipe. And Mac 3" exhaust. Don't forget I also have a 4 valve motor. Don't know if ur trying to get the same sound but don't think u can on a 2 valve.
