Seems like I've asked this before but my memory stinks so I'll ask it again........

Does anyone have dyno sheets that show a horsepower gain with ONLY an exhaust change? I suspect that often a change in the exhaust noise level leads some folks to "feel" like the car has more power. I call it "Placebo GT speed parts".
