The Nissan Armada SUV and Titan trucks are well known to have the exhaust header cracks. This is very noticeable when you start a cold engine. I gets better as the engine warms up.
Repair involves removing two engine mount bolts, jacking up the engine, removing the heat shield from the manifolds, them removing the manifolds themselves.
Some aftermarket manifolds give good results but the engine ECM has to be reprogrammed. Some have reported success with welding the leaks.
On the extreme are some people who have reported success using some form of high temperature JB Weld.
This video is just to help you hear the sound and know if you’re car has the same symptom.
