Smog-control affect on performance
Could someone explain all the ways (or at least as
many ways that you can think of) that pollution
control devices have hurt performance. I know that
engines are smaller, and the catalytic converter
corks up the exhaust flow, but that's about all I
really understand. Can someone elaborate for me?
I've heard that you can't compare the
horsepower/torque ratings for the old muscle cars
with those of today. Something about they use
different standards. Can someone explain that?
