what headers are a direct replacment for the headers on my 93 5.0? i've set up the exhaust past the headers...i was told (by my dad) that it already had AFM headers...lair
...anyways I want to replace the restrictive lil demons...any suggestions? i dont want to spend anything more than 250 or so...i was thinking shortys because that seems the only kind that will work (but i'm not sure) without messing with the rest of the system...I have the stock collectors still...what should i look for when buying headers? thickness? collector diameter?...and what gains might i experience?
