What Our Customers are Saying

… I have had the opportunity to work with Freddy on more than one occasion and, whatever the duration of the job, Freddy has displayed his technical knowledge in a very helpful, personable and straight forward way …

Jorge and the DeAngelo team upgraded our exhaust system, and the result is much better than the original. We particularly appreciated the choice of Inconel metal

I know of numerous prestigious builders that use their systems and they are the only company I recommend to clients and yacht manufacturers … I give a full unquestionable recommendation for DeAngelo Marine Exhaust …

Our company’s experience with DeAngelo Marine Exhaust was superb in all respects, especially quality of finished product.

I would like to thank you for doing a great job on the new wet injection exhaust elbows for the San Juan 48 “Seawalker”. Your newly manufactured parts fit perfectly!
