not plug and play. you have to get a 20ohm 20 watt resistor if the o2 has four wires and cut the plug off the old o2 and put it on the simulator. i would find the wires up in the engine area and do it. for hiding and vibration snow etc. make sure you solder your connections.

What good would it be to make a simulator if you stil have to add parts to it to make it work?

some have the heater for the o2 some dont. if your car does you can either leave the heater part hooked up or bypass it with a 20ohm 20w resistor.

Update: Got everything welded up! Took the gold pin stripe off the sides and put in some silverstar "chrome" turn signal bulbs . This was before I washed it... I'll get some better pics tm up in the my ride section.

Looks good! I've been running a Magnaflow direct fit cat on the GP since November '07, and it'* passed emissions twice without any issues. It was a good bang for the buck upgrade.

Looks really cool. How about a video so we can hear it?
