OK, im a newbie to the v6 power arena and so far have found myself quite impressed with v6 bolt ons for the almighty mustang. considering that its low man on the mustang totem poll and more people just trade up the line (ex: OxMox). Heres my delema my wife doesnt want to trade out of her V6...now so i get about 600 to finish her car off with. As with most wifes theres a catch, it has to increase power it needs to make the engine and exhaust go...and i quote "BOOM"
(but i love her anyways
). so...i've done the search...and the research with these conclusions as i live in Florida and smog or emissions test are not happening anymore so im going/leaning with longtube headers and a diablo chip. The long tubes add from best i can tell 15 horses or so and the added sound she demands. The snag is there are no long tube for the 98
never easy is it? so heres the question.....finally......Can i modefy the 97 longtubes to the 98 fairly easily. Mac has an awesome set for a desent price at V6mustangstuff.com $259 free shipping i think. but like always no fit 98 V6 just up to 97. i have heard rumors the only diff. is the EGR tube needs modify if so project on!!!!!
but i get one shot at this and of the 5 "mustang guys" at local shops and e-mails with vendor sites they will not match and modefying is virtually impossable. SO please help a 4.6 guy with a stupid newbie question
