Just out of curiosity, has anyone quantify the benefits of horsepower gains with respect to exhaust ?

I'm not talking about dyno readings. There are ways to "bump up" horsepower figures.

I'm talking about controlled test on 1/4 mile times on both Stock and Aftermarket. Same track, ambient/surface temps, driver, etc.

Reason I ask is because I see a lot of dyno charts but if 1/4 mile times are the same stock mufflers, I don't see how a 100hp gain on dyno translate to any form of benefit.
