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.

+1

5 years on my CMI with no issues,

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

That's the way to go.

stainless marine they last for years, I know guys with them after 11 and 13 years of running them in salt and lake just keep going and going. good hp gains

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.

Stainless Marine! using a set off a boat I had in 95' still good, best money I ever spent........................................Rjr.. ................................
