Marine Exhaust

Welcome to the "NEW" evolution in economical performance exhaust systems. By utilizing the latest advancements in lost foam casting manufacturing technology, this new cast aluminum manifold is a cost effective solution to your performance exhaust needs.

The lost foam casting process provides a product that is stronger and more precise with a composition that is many times denser than traditional castings. These denser castings have a corrosion resistance nearly 200 times more resistant and are even lighter in weight than manifolds manufactured with traditional sand casting.

In order for a performance exhaust system to deliver increased power it must not only lower the exhaust back pressure but also provide for true separated exhaust pulses in order to properly scavenge the exhaust. This new evolution manifold does both.

Standard systems are available with an OEM style cast aluminum riser that is powder coated to match the manifolds. For maximum durability and the highest level of performance polished 316L stainless risers for either standard thru-hull exhaust or silent choice applications are available.

Each exhaust system comes complete with our "NO WORRY" installation package that includes all necessary hardware, gaskets, bolts and shift quadrant cable connection provisions. You won't find a smoother installation than this.
