So ive taken my 2004 f150 5.4 scab to the dealership 2 times and gotten it Diagnosed because theres some kinda ticking sound, theres no trouble codes popping up and the 2nd time I took it, they said that it sounds like theres a hole in my passenger side header/manifold or whatever it is that is stock. now im faced with getting a new header and wondering whats a good brand to go with, im going to upgrade the exhaust while im there and wondering whats good thats out there, I dont wanna straight pipe it because Ive got that whole government exhaust bull**** that we call Aircare here in British Columbia. does anyone know if some good brands that I should go with, or is it just preference..

 

my 03 started that ticking noise few weeks later my truck shot a spark plug out..
