Hey guys. I talked to Mike T. and he instructed me to purchase a set of Dynatech Headers for my '97 5.4 4x4. I then called dynatech after I had talked to Mike and they said that the header and Y pipe system they make is only for the 99-03 trucks. What is the deal with that? Why will the dynatech system not fit on my 97? What is different? I know I have the non-PI heads on my truck but I would think that everything is just a bolt on issue. Whats the deal? Has anyone had this issue...? Why will they not fit...?

 

Anyone have this problem? Anyone?
