Headers or Manifolds?
I have a 1972 c10 with 2 inch true dual exhaust and a stock 350 I intend on eventually upgrading when I have money, my exhaust needs to get refitted to my manifolds since something is wrong so I figured if they are going to change it is it worth it to upgrade to headers? Mainly used as a weekend/summer cruiser so is it worth the hassle of headers? Also is the fuel mileage increase going to be noticeable?
