Exhaust question...
2003 Outlander AWD has a Oxygen sensor in front an behind the catalytic converter, I'm in Alberta Canada and we have no emissions control, so I was thinking do ditch the CAT and replace it with a straight pipe. Now since there are two sensors and they pick up signals before and after the CAT will my CAT removal cause some unwanted effects like "check engine" or running lean\rich.
If anyone has done this could you please shine some info my way? THNX.

I did this with our Nissan Quest, which we used to have. First few years all was well. Than the engine started backfiring and losing power going uphill and pulling our trailer. The dealer installed a new converter and the van ran like new. Something about the computer running out of "room" to compensate for the lack of converter. I will never pull out the converter again.

RE: Exhaust question...
Removing the cat will give you a down stream o2 sensor fauiler code. The ecu will think that either the car is running too rich or its running with an exaust leek. The the ecu will lean the a/f ratio out to a safe degree. In short the car will become a little faster but you will have a cel. Their are a few tricks you can do to get rid of it. For the eclipse you can put a 1/2watt, 1000 ohm resistor in the sending line of the 02 sensor and the code will go away.
