Default Thinking About Ford Raceing Shorty Headers M9430-s197

I'm thinking of purchasing these shorty headers and would like to know what I can expect as far as horsepower and sound with the stock mufflers and any other benefit I might get out of installing these on my 2010 GT

Thanks

Shorties provide little bang-for-the-buck and iinstall time. You'll be lucky to see more than single digit RWHP gains; probably even luckier to see more than 5. You'll probably notice a slightly deeper tone but nothing to write home about.
