4.9 straight six... Manifolds vs. Headers?
Hey guys. I have a 93 ford f150 with the 4.9. The truck has always had a n exhaust tick. I believe it is the manifolds. I want to fix this tick and I was wondering if I should
Just replace the manifolds, or should I throw headers on it while I have the old manifolds off? Also if I
Put headers on then I don't think I could use the
Stock cats?
