Photo 3/16 | 2007 Nissan Frontier wheels Removed | The Install 1. Installing the headers is most difficult on the passenger side of the Frontier, so that's where we'll focus our attention. First things first, the wheel was removed and the truck raised into the air with a hydraulic lift (a jack can also be used).

Once the piping is off the hanger, it can be pushed backward about an inch. Then, the 12mm nuts can be undone and the converters can be pulled from the exhaust manifolds.

Photo 8/16 | 2007 Nissan Frontier unbolting Motor Mount | 5a. A 12-inch-long extension and 18mm socket were used to unbolt the motor mount from the frame.
Photo 9/16 | 2007 Nissan Frontier jack | 5b. A jack was used to raise the engine up just high enough to pull out the manifold from the engine bay.
Photo 10/16 | 2007 Nissan Frontier blue Colored Socket | 6. If you look closely, you'll spot the blue-colored socket attached to the air ratchet that was used to remove the six nuts holding the manifold to the cylinder head. The nuts are soft and easily rounded off, so a swivel union behind the socket was necessary for removal.
Photo 11/16 | 2007 Nissan Frontier sealant Smeared | 7a. Before the new headers were installed, the multilayer copper gaskets were smeared with sealant around the exhaust ports to ensure a leak-free fit.
Photo 12/16 | 2007 Nissan Frontier flange | 7b. The bolts were tightened in sequence working from the inside of the flange to the outside, which applies equal pressure to the flange for a good seal to the gasket.
