I don't understand.  If it were so easy to add HP with no other adverse
effects, the manufacturers would do it.  Sure, in the old days, one
could add headers and change mufflers and get free horsepower.  But how
many engines then put out 100 HP/liter (e.g. the S4)?  Most modern
German cars already have header-type exhausts _and_ larger pipes.  Many
even have multiple cats, so the increased HP obtained by bastardizing
the exhaust system will come at the price of noise and/or air

If car manufacturers were at all capable of stalling progress, we'd
still be driving around on bias-ply tyres!

While all these pollution regulations do sound ridiculous to those
living in less-populous areas, they make sense to us NJ residents.  In
fact, the county in which I live and work is one of the many which
exceed federal pollution limits by >20%, and believe me, this is a
problem, especially on hot summer days.  Since there are still many
older, high-polluting vehicles on the road and nothing can be done
about that, they are instituting a Employee Trip Reduction Plan, which
is basically forced carpooling.  As more counties exceed pollution 
limits, this plan and more like it will be imposed on those counties.

So even though I can afford to drive a low-pollution new car, I soon
won't be allowed to because others have chosen to save money by driving
high-pollution cars either out of necessity or choice.  Just going into
town at lunch, an old pickup truck in front of us brought tears to our
eyes and probably many others in the small town where I work.

The basic problem is that the low price of gasoline does not reflect
the total economic cost associated with its consumption, which many
analyses have shown to be over $5/gallon.  Remember that every day,
American drivers alone travel the total distance from the Earth to
Pluto and back!  Mankind is no longer insignificant in the total
picture of the universe.
