Big Boss Exhaust Manifold CAT C15/Emodel Low Mount Ceramic Coated Black

This black ceramic-coated 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.

It is the low-mount version, which places the turbo connection in that mounting position. 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. The black finish suits an engine bay where a darker appearance is preferred.
