I have a 2011 PRO 4X with 121,000 miles (yes I know I drive a lot) When I started it this morning I could hear the leak. I stop by my local Nissan and they said both manifolds are cracked. The truck is stock but I was thinking of added some nice headers since they need to be replaced and it is out of warranty. The stock replacements are $3100 with labor.

What do you all suggest for replacement? I dont want any check engine lights and not to loud.


thanks for your help.
