Big Boss Exhaust Manifold CAT C15/Emodel Non-coated

This uncoated PDI Big Boss exhaust manifold collects exhaust from CAT C15 cylinders and directs it to the turbocharger. It replaces the manifold at the engine’s exhaust ports and provides the connection between the cylinder head and turbo system.

The manifold joins the separate exhaust-port outlets into the turbo’s incoming gas path. A sound manifold keeps that route sealed, making it a replacement option when the original casting or connections are damaged.
