Hardin Marine has shared some additional details on their new Seaward Exhaust Systems that they will be debuting at the Miami Boat Show. Read on for more details…

The Seaward exhaust systems will be the biggest performance market changing product to debut in 2016 according to them. These exhaust systems were not only created using the most modern robotic electronic machine operations but with state of the art tooling. What does all of this mean? It means you can now buy the very best and reliable performance exhaust manifold system that money can buy for a whole lot less money.

The SEAWARD debut is a 100% all new design. These exhaust systems were built to provide virtually every feature once desired in a performance marine exhaust system with reliability and longevity the most important features. This is just the beginning as we made sure that this is a direct replacement bolt-on manifold for all late model GM Big Block engines. The hint is that there will be even more versions debuted in Miami.

Here’s the facts: There is no other performance exhaust manifold system on the market today with as many features and advancements in construction PERIOD. Starting with a 356T Heat treated tubular style cast internal core that has been optimized to flow with the technology, shape, and design of a tubular header. By extending the runners and separating the exhaust pulses to the collector this system produces maximum power in a compact design.


More Facts: 1000 hour salt spray coating. That’s right this industry has never seen these types of processes. These products are extending the naval and aerospace program products as much as ten years. Sure the finish is that of a show piece but it’s truly what you can’t see that sets these systems apart. Underneath the thick non-porous billet heat treated aluminum casing lies the most exceptional foundation of corrosion protection found anywhere. A hydrogen infused zinc process is applied to each manifold. Until now salt spray testing could merely only withstand 100-150 hours of sustained exposure, yet today with these new improvements those numbers are upwards of 1000 hours of durability.


More facts: Beauty is well beyond skin deep here as the beautifully polished stainless steel exhaust risers of the systems are manufactured from 316L Stainless Steel while inferior systems choose inferior stainless (303/304 Auto Grade) steel, Seaward systems offer nothing but the best money can buy which has been proven to be the most durable long lasting product for marine use.
