Can you change in-board exhaust risers to just headers?

Question

I have a 350 mag with exhaust risers on it. I think they are clogging up and I was wondering if I could do away with the risers and go to just headers?

Answer 1

not automotive headers, but marine water-cooled headers, yeah.  Captain's Choice is a common set.  look them up.

Answer 2

Straight headers cannot be used as part of the cooling system flows through the manifolds and out the risers to keep the manifolds cool. There are aftermarket marine manifolds more performance orientated that are available. What makes you think the risers are clogging? If they were there would be poor water flow out your exhaust and the engine would start to overheat. If it is a performance issue let us know what the issue is.

Answer 3

Google  Gil Marine. They are the largest of marine headers in the business

Answer 4

NO.

Answer 5

No the water has to flow threw to cool>
