  Hold your breath for as long as you can, and don't eat anything
either. You'll find out in "short order".

  As for "ruining" a car, get your mind out of the sixties. Modern
catalytic converters are VERY inobtrusive. There is effectively
nil gain in removing it from a modern car, unless you need to
remove it to replace the exhaust from the engine back with something
much larger than the cat.

  So, it's ok to do whatever you want to the air as long as
you can't get fined for it?  The laws enforce common sense, without
the laws it's still common sense.

  Not really true. Obviously computer control helps in any finely
tuned emissions system, but it's not essential. Although I've never
owned one, late LBCs have catalytic converters with common
carbeuretors.

  You don't need any of this. Look at the catalytic converter
on any modern car, it's totally passive. All it needs to work
is exhaust heat.

  The oxygen sensor, feedback loop, and ECU is only if he
wants to convert to EFI. This is a wonderful project, which
I am in the middle of myself, but it's a seperate goal.

  I applaud the effort.
