Will my 08 crown vic p71 run well without catalytic. converters.
Only if you do all of the O2 sensor modifications, but it won't pass inspection if your state requires it.
It will run however emission test will fail. Some vehicles after removing some parts won't start until disabled from computer thus a diagnostic test is needed.
How does it perform on long trips?
