I live in the salty Midwest, where headers don't last long. Was just on a thread that mentioned 1999+ have better flowing manifolds. I've got a 98 4.3, does anyone know do the newer ones flow alot better. Much like the old "Rams Horns" back when. As atleast they won't rust out in two years.

if your having issues with rusting out your headers, and you dont wanna run stock logs id pony up the cash and go stainless......cast manifolds really havent changed much.
