True.....if the cat is before the O2 sensor. Some Rangers, like my 03, have a cat AFTER the O2 sensor.
I'm still not sure if I'll take a cat out.....just thinking out loud.

why would you do this? you will see no gain in power and it will sound like ***, hollowing a converter makes it an echo chamber and the exhaust pulses get screwed up bigtime. plus its bad for the enviorment

On a stock motor limited to stock rpms your not going to see much if any power improvements in the *normal* driving rpms.
These motors are short stroke motors. So in the 1000 to 3000 rpm area (where we spend most of our time) there really is not that much air moved.
If you spent time in the 3000+ rpms.. then you would see some power improvements. But come on.. how many "4.0L rangers" spend time up in those areas?
