There is an Excel spreadsheet on here someplace that shows dyno results from various exhaust headers like CMI, Eickert, etc. It had tables and graphs. Can somebody post a link to it please if you know where it is? Thanks

A boat Magazine, maybe Hotboat, had an article abut this. There was a graff in the article.
Or maybe it was Family and Performance Boating

Found that spreadsheet, if anyone can post a .xls file please tell me how and I'll post it. Thanks
