So, I bought my 2006 5.9 back in February. I know all vehicles have their own issues. So, I came across the article above and wanted to get some more opinions on it. As far as I know there are no modifications under the hood, except a new intake. Should I seriously consider getting an aftermarket exhaust manifold? For reference, the truck has 291k miles.
