How the heck did we get talking about manifolds here anyways? Wasn't the question about headers? The fact is Yes S/M Gen 3 manifolds are excellent quality and perform super and Brownie is quite possibly the nicest guy in the world. But we were talking about headers. A little clarification here "Dry" means no water enters the exhaust stream. The pipes are still water jacketed thus cooled. No water in the exhaust stream means no-reversion. Most engines once again "MOST" engines with a camshaft exceeding .240 of duration @.050 will require a dry exhaust system. Thus anything making more than about 650 horsepower with a header will likely require a dry tailpipe.

For what its worth I thought I could add my 2 cents.... I have used both wet and dry Lightning systems and have been very pleased them. I used the standard (wet) system on a stock internals 454 mag for more than 600hrs with no issues of corrosion or faulty craftsmanship. I boat in freshwater only and drain them after each use. Currently, due to cam profiles and HP numbers as CP Performance mentioned I am using Lightnings (dry) system. Although I have not used headers by another manufacturer, I would highly recommend Lightnings based on my experience with them.
