Gain access to the manifold area, Unbolt the 6 bolts holding it on. Seperate the manifold from the engine and scrape off the old gasket, sand it down with emery cloth, Make sure to keep debris from going inside the chamber. Insert the new gasket and get the manifold close then wiggle it around till you can get a few bolts in then thread the rest in. torque them down to spec and your done.

To replace the exhaust manifold gaskets on a 2006 Nissan Titan, first, disconnect the negative battery terminal and remove any components obstructing access to the exhaust manifold, such as heat shields or intake parts. Then, unbolt the exhaust manifold from the cylinder head and carefully remove the old gaskets. Clean the mating surfaces thoroughly before placing new gaskets and reassembling the manifold, ensuring all bolts are torqued to the manufacturer's specifications. Finally, reconnect any removed components and the negative battery terminal.

there are two cat one iswielded with the exhaust manifold and the 2nd is connected to the exhaust manifold with the o2 sensor leading to the exhaust.
If the engine knocks when it is cold, it might be a crack in the exhaust manifold, or possibly a crack in on of the exhaust manifold bolts leading to the block. The crack is small, and once warm will swell shut, thereby stopping the noise. Without repair, it might lead to valve exhaust valve damage.
follow your exhaust from your exhaust manifold and you will find.
It is in the exhaust pipe right after the exhaust manifold.
Most likely it is the exhaust manifold leaking, which is very common on this model with the V6 engine. It is usually most noticable when the engine is cold, and gets better as it warms up.
To repair the exhaust manifold on a 2005 Nissan Armada, first, ensure the engine is cool and disconnect the battery. Remove the necessary components, including any heat shields or exhaust pipes, to access the manifold. Inspect for cracks or damage, and if needed, replace the manifold with a new or refurbished one, ensuring all gaskets are replaced. Finally, reassemble everything, reconnect the battery, and start the engine to check for leaks.
