Earplugs increase horsepower!

[nomadwest]

Now I now that sounds dumb but for those who wear earplugs like me when your on the highway or interstate and have Vance & Hines exhaust, have you ever noticed that your bike just seems smoother and faster when you have earplugs in? I have thought about changing my exhaust back to stock a number of times, but I love the sound around town and at idle and I know I would miss the increase Iive gained in performance. So I guess I will just use earplugs when I want to smooth out the ride.
