I am looking into redoing my whole exhaust and just about everywhere I look, there are different options for headers on the V6 stangs. '99-'00 differ from header options for '01-'04. I have a 2000 and want to keep my EGR and thus buy headers with EGR but the only options for headers are of that for '01-'04 and I am just wondering why they wouldn't work for my '00 model. Bolting the two up should be the same right? Why is it that I can't find header options for '99-'00 V6 stangs WITH EGR?
