I have a 454 EFI Mag that has recently been gone over and for the most part is stock except for the intake has been ported by Lingenfelter and a vortech air intake. I want to know which exhaust manifolds work best with this engine has a great look and won't kill my wallet again. PS. It's a straight thru hull corsa exhaust system now. Thanks for any suggestions ,Darby

Best bang for the buck,Eddie Marine, Dana Marine, Stainless Marine would be the next step up but more expensive. The best is Keith Eickert Exhaust. I will give you a great deal on any one you choose.

Check into revolutions. I have them and love them. Least expensive of the performance manifolds.
