I have a crack in my passenger side manifold on my 5.4. Sounds horrible. I would say on a scale of 1-10 it's at least an 8 to remove and fix. I don't even know how you get to some of the bolts. Going to cost around $750 at ford to fix. Or long tubes with off road y pipe installed locally plus programmer will be close to $1000
Mine sounds like crap too. I've been doing some research on the 5.4's and this looks like a common problem. Biggest issue with the fix is breaking off the studs. It looks like you can gain some access to the lower nuts by removing the starter. Top nuts look straight forward. I've got another forum member who is willing to tackle this with me. Going to get a couple of quotes tomorrow. If its under $500, I'm going to let someone else fix it. Then it goes up for sale! Time for that new 2014.
