Why Upgrade Your Exhaust Manifold?
Before diving into the installation process, let’s discuss why you might want to upgrade your exhaust manifold:
Improved Air Flow: Aftermarket manifolds are designed to optimize exhaust flow, reducing back pressure and increasing fuel mileage efficiency.
Increased Durability: Thicker exhaust flanges and center divides provide greater strength and durability for even the hardest working trucks.
Here’s a step-by-step guide to installing one of our exhaust manifolds:

b. Use the factory tightening sequence
4. If necessary, replace the thermostat housing using new gaskets
5. Reinstall turbo and torque to proper specifications
6. Reinstall the oil lines and reconnect the exhaust tubing
7. Reconnect the air-to-air tube
