I don't think Harley owners think of performance when they open up their pipes. I think it is about ticking others off.

Nope, we call it paying the tax. Harley's are crippled off the showroom floor, and I mean crippled. Often times you can get a 20%-25% boost in horsepower by paying the tax, ie, high-flow airbox, high-flow pipes, and rejetting the carburator to accomodate both.

Harley's are crippled off the showroom floor,

Why? (I have a guess)
