The Exhaust Manifold Set GM LS Swap Cast SS Polished provides a high-performance solution for marine enthusiasts looking to modernize their vessels with a GM LS-series engine. This Hooker BlackHeart series manifold set is engineered to facilitate seamless engine conversions while maintaining the durability required for harsh aquatic environments. Boaters often seek these manifolds to replace bulky factory cast iron units that are prone to corrosion and excessive heat retention.

Constructed from premium cast stainless steel, the Exhaust Manifold Set GM LS Swap Cast SS Polished features a 2.5-inch outlet designed to optimize exhaust flow and reduce backpressure. The cast design offers superior strength and heat management compared to traditional tubular headers, which can be susceptible to cracking under the thermal stress of high-load marine applications. The polished finish provides an extra layer of protection against the elements while significantly enhancing the visual appeal of the powertrain. These manifolds are sold as a pair, ensuring a matched set for both the port and starboard sides of your GM LS-series engine block.

This manifold set is specifically tailored for those performing a GM LS-series swap in marine or custom automotive configurations where clearance and reliability are paramount. The compact design ensures compatibility with a wide range of hull types and engine compartments, making it a top choice for builders seeking specifications that balance fitment and power. Installation is straightforward for experienced mechanics, providing a reliable connection point for the rest of your 2.5-inch exhaust system. Whether you are upgrading a classic boat or building a high-speed cruiser, these manifolds deliver the performance and longevity expected from the Hooker BlackHeart line.
