Exhaust kit for a Mercruiser small block V8 engine with a 3 inch spacer. This kit includes the manifolds, spacers and risers along with the gaskets and mounting kits necessary for installation.

The parts in this kit are made from Aluminum and have a proprietary, patented process by which Ceramic Material is molecularly infused into the INTERNAL AND EXTERNAL surfaces for the best possible corrosion resistance available with ANY cast marine exhaust system! How do you know this is true? How about a 5 year warranty!

NOTE: If you currently have stainless steel risers you will need to order the updated Remote Oil Bracket and fasteners to upgrade to the later riser design that is included in this kit.

* 5 Year Warranty requires purchasing the separate anode (1 per manifold) on an annual basis.
