does anyone know where i can get an o2 sensor simulator? i looked on google but all i could find was websites about what they do

will be very hard to find now. the only company i knew that was making them was Casper (i think) and they got basically forced out of business by the state of California and the US gov't.

are you deleting your Cat? what alot of people have been doing instead of running a simulator is running the O2 Sensor, but using an O2 sensor fouler to space the O2 sensor further out of the exhaust stream so it doesnt see an excessive amount of gasses and throw codes.

well i have an open manifold so it was just dragging on the ground and eventually fell off, now that put putting the cat and resonator back on just because its too obnoxious for me i figured id put it back in but even when it was still on there it was fried, and my buddy told me the mock up ones were cheaper than like 70-80 bucks so i figured id do that
