502 replacement manifolds
 
What is the best "bang for the buck" when replacing 502 manifolds. Would like to get the entire kit needed to replace the stock manifolds with performance ones. Looking for recommendations.

Stainless Marine; 5yr warranty.

Considering recent threads on aftermarket exhaust manifold performance gains, I would look at Revolution Marine as the best bang for the Buck

Do you boat in salt water? And what is your budget/performance gains?

I have a set of used Stainless Manifolds taken off 502 MAG MPI's.

PM Me for details.

Yes I run in salt 5% of the time, the rest is fresh water. I would like to do it all for less than $1500.

Although my personal preference is to the KE exhaust, since you mentioned "bang for the buck", I would have to agree with many on this thread. The Stainless Marine cast exhaust should be your choice.

I did a fair amount of research before choosing the exhaust for my 502 and the Stainless unit is a stout piece.

Forget about your budget line and just go out and shop your best price. In 5 years you will be thanking yourself (length of the warranty period).

Dana Marine Torque Flows seem to be a pretty good bang for the buck plus they look pretty cool. So far i haven't head anything bad about and I've researched them several times on here.
