I understand that CMI is releasing a header, or modifying the existing 496 version to work with the Corsa silent choice. This was my only hesitation previously, with all the new laws etc., I hate to lose that option, as well as using the boat so much late at night.
I am game to try these, hard to believe no one else has. I hit the upper 70's with the shorty (and lab prop), if the predictions are true with these headers, it would be an 80-82 - 496 boat. Sure would be nice to know if the claims of 50-60 hp, and the 3-5 mph are true first. Do I have to be the "registry" Guiana pig LOL.
