If you've got a big block Chevy-powered jet boat, especially a nasty 496, and you want it to breathe fire, these Speed Daddy stainless steel exhaust manifolds are what you need.
They're built for marine performance, specifically for v-drive jet boat applications.
These aren't your grandpa's cast iron manifolds.
They're made from full T-304 stainless steel, with a chrome-polished finish that looks absolutely killer.
They flow way better than stock, which means more power and that sweet, deep marine V8 rumble.
This is a performance/custom fitment, so make sure your setup is ready.
They're brand new, part number SDD-HDSBB.
Just a heads up, they can't be shipped to California, Maine, or New York due to emissions stuff, and there's a Prop 65 warning because, well, chrome and chemicals.
But if you're building a high-performance jet boat and you want the best-looking, best-flowing headers on the water, these Speed Daddy manifolds are a top choice.
