i took my convertors off for a while, it didnt cause any backfires or missfires, however i did seem to loose some low end power belive it or not. it may help boost hp on a beefed up v-8 or a turbo car, but on the 2.9 it didnt. i have since replaced mine with new ones. what about emissions? it wont pass the visual inspection with a straight pipe.

I gutted out my cats, and I lost some of the low-end power, but I also gained some of the higher-RPM power. I haven't had any backfires or missfires at all though.
