Hydrocarbon fury

There's no denying that image is a huge factor in vehicle selection. We fork over big bucks for a ride that will not only get us and our stuff from Point A to Point B, but will also make a statement about the person behind the wheel.

Take this pickup, for example. Shiny red paint! Overt display of patriotism! Oversized rubber! And... check out that exhaust pipe! It's so big that you could store your CD collection in there! It must take quite the man, to even handle all that barely-contained raging fury when the gas pedal is punched!

Hey! Wait just one minute!

Upon closer inspection... that huge exhaust pipe is just pretend! It's just bolted on the end of a much more conventional-sized exhaust pipe.

I'm no internal-combustion engineer... but it seems to me that this giant chrome exhaust tip wouldn't add even a single horse power! Am I wrong? I invite expert opinions that might clarify my misunderstanding, if there is one.

Is this exhaust tip the vehicular equivalent of sticking a cucumber down your tight britches?
