Suggestions Wanted For 408 Stroker Mufflers

Hi Guys, somewhere their is a Flow sheet of all the popular performance mufflers tested for total flow. I think it's maybe on the Dyno Max page. Don't remember but many of the popular street/race muffs were tested and the results were very interesting as I have used many of perf. muffs sense very early 70's. Hope you all can find it. I just purchased the 3" dyno max a couple years ago and have a 40" straight before the muffs/tail pipes for helping scavenge. Good Luck
