Exhaust manifold leak

Ugh. I've been hearing this whistling sound and being new to diesels always thought it was just the turbo. But recently I've been getting a whiff of exhaust in the cab on first start. I thought maybe I hadn't mated up the down pipe with the turbo very well when I installed the 4" exhaust so I checked that and it's nice and clean. Then I checked the up-pipe bellows and connections and those are clean as well. But then I see this on the passenger side exhaust manifold:

It must not be affecting boost to much because I can hit 27psi.

I have a Zurich extended warranty but also have a 4" turbo back exhaust that I added after I purchased the truck. Do you think they'll give me a hard time about fixing it? Or am I stuck fixing this myself? And if I have to fix it myself how hard is it to do?

If you're going to do it do it right. Get new manifolds, bolts, collars and add gaskets. They don't come with gaskets from the factory but they are needed for a leak free connection.

The manifolds are not extremely difficult to access. For the passanger side you will need to remove the inner fenderwell. The front 2 bolts near the A/C compressor can be tricky but not impossible. All the drivers side manifold bolts can be accessed from underneath and removing the inner fenderwell doesn't really help.
